How do the graphs of \(f(x)\) and \(f(x)+10\) differ?

Short Answer

Expert verified
The graph of \(f(x) + 10\) is the graph of \(f(x)\) shifted 10 units up.

Step by step solution

01

Understanding the Functions

We are given a function \(f(x)\) and a new function \(f(x) + 10\). The task is to understand how the graph of \(f(x)\) changes when transformed into \(f(x) + 10\).
02

Identify the Type of Transformation

Adding a constant to a function, such as \(f(x) + 10\), results in a vertical shift. The entire graph of \(f(x)\) will move upwards by the constant value, which is 10 in this case.
03

Apply the Vertical Shift

For every point \((x, y)\) on the graph of the original function \(f(x)\), the corresponding point on the graph of \(f(x) + 10\) will be \((x, y+10)\). This means each point is shifted straight up by 10 units along the y-axis.
04

Graphical Interpretation

If the original graph of \(f(x)\) is plotted, imagine lifting the entire graph upwards without changing its shape. This transformation does not affect the horizontal position of any point on the graph, only the vertical position by 10 units.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Vertical Shift
A vertical shift is a fundamental concept in function transformations, where every point of a graph is moved up or down by a certain amount. When examining the function transformation from \(f(x)\) to \(f(x) + 10\), the additional constant, which is 10 in this case, signifies the shift distance along the y-axis. Imagine taking a transparent sheet with your graph drawn on it, and moving it vertically upwards by 10 units. This visual can help cement the concept of vertical shifts. The underlying rule is simple:
  • A positive constant moves the graph upwards.
  • A negative constant would move it downwards.
The effect on each point \((x, y)\) is straightforward; it now sits at \((x, y+10)\). This move doesn't change the function’s shape. There's no distortion, just a uniform upward translation.
Graphical Interpretation
To effectively interpret the graphical transformation, envision the graph of your base function \(f(x)\). Now consider overlaying this graph onto a coordinate plane. The transformation into \(f(x) + 10\) means that every point on the graph rises by 10 units. This transformation can be visualized step by step. At each coordinate, increase the y-value by 10 while keeping the x-value constant. This provides a precise method to accurately envision how the graph has changed. In graphical terms:
  • The overall graph maintains its orientation and relative distances between points.
  • No x-direction (horizontal) shifts occur.
  • The shape or curvature of the oginal function, \(f(x)\), does not alter.
Visual changes occur solely in the vertical positioning, underscoring the vertical shift concept.
Algebraic Functions
Algebraic functions are expressions built using polynomial equations, typically involving constants, variables, and arithmetic operations. These are the types of functions most often subjected to transformations, like the vertical shift discussed here.Consider a simple linear function \(f(x) = x\). If we apply a vertical shift by adding 10, it becomes \(f(x) + 10 = x + 10\). The value of the variable x determines the linear relationship, while the +10 adjusts every output by a constant amount, independent of x.Some useful aspects of algebraic function transformations include:
  • The ability to predict and control graph movements using functions.
  • Understanding how different operations affect graph geometry and positioning.
  • Comprehending these shifts aids in analytical tasks and problem-solving strategies where function manipulation is integral.
The comprehension of algebraic functions extends into numerous mathematical and practical applications, underscoring the importance of grasping these shifts.

BEHAVIORAL SCIENCES: Smoking and Education According to a study, the probability that a smoker will quit smoking increases with the smoker's educational level. The probability (expressed as a percent) that a smoker with \(x\) years of education will quit is approximately \(y=0.831 x^{2}-18.1 x+137.3\) (for \(10 \leq x \leq 16\) ). a. Graph this curve on the window [10,16] by [0,100] . b. Find the probability that a high school graduate smoker \((x=12)\) will quit. c. Find the probability that a college graduate smoker \((x=16)\) will quit.

Find the intersection point \((L, K)\) of each isocost and isoquant. [Hint: After substituting the second expression into the first, multiply through by \(L\) and factor.] $$ 3 L+8 K=48 \text { and } K=24 \cdot L^{-1} $$

GENERAL: Tsunamis The speed of a tsunami (popularly known as a tidal wave, although it has nothing whatever to do with tides) depends on the depth of the water through which it is traveling. At a depth of \(d\) feet, the speed of a tsunami will be \(s(d)=3.86 \sqrt{d}\) miles per hour. Find the speed of a tsunami in the Pacific basin where the average depth is 15,000 feet.
