Chapter 2: Problem 58

Begin by graphing the standard quadratic function, \(f(x)=x^{2} .\) Then use transformations of this graph to graph the given function. $$h(x)=-(x-1)^{2}$$

Short Answer

Expert verified
For the given function \( h(x)=-(x-1)^{2} \), graph shows a parabola, originally at the origin, that has been shifted 1 unit to the right and reflected over the x-axis.

Step by step solution

01

Graphing The Standard Quadratic Function

Start by plotting \( f(x)=x^{2} \). This is a basic quadratic function which forms a parabola opening upwards. The vertex or the minimum point of this parabola is at the origin (0,0). For a better understanding of the function behavior, points on either side of the vertex can be plotted. Typically, some easy-to-calculate points such as (-2,4), (-1,1), (0,0), (1,1), and (2,4) are chosen.
02

Identify The Transformation Of The Given Function

The given function is \( h(x)=-(x-1)^{2} \). When comparing this function to the standard quadratic form, \( ax^2+bx+c \), it's clear that there are transformations. Specifically, the transformations include a horizontal shift to the right by 1 unit and a vertical reflection over the x-axis.
03

Applying Transformations To The Graph

Applying the identified transformations to the original graph, the parabola is moved 1 unit to the right (the vertex becomes (1,0)) and then reflected over the x-axis, as the negative sign indicates.

use a graphing utility to graph each function. Use \(a[-5,5,1]\) by \([-5,5,1]\) viewing rectangle. Then find the intervals on which the function is increasing, decreasing, or constant. $$ g(x)=\left|4-x^{2}\right| $$

The bar graph shows your chances of surviving to various ages once you reach 60 The functions $$ \begin{aligned} f(x) &=-2.9 x+286 \\ \text { and } g(x) &=0.01 x^{2}-4.9 x+370 \end{aligned} $$ model the chance, as a percent, that a 60 -year-old will survive to age \(x .\) Use this information to solve Exercises \(101-102\) a. Find and interpret \(f(90)\) b. Find and interpret \(g(90)\) c. Which function serves as a better model for the chance of surviving to age \(90 ?\)

The function $$ f(x)=-0.00002 x^{3}+0.008 x^{2}-0.3 x+6.95 $$ models the number of annual physician visits, \(f(x),\) by a person of age \(x .\) Graph the function in a \([0,100,5]\) by \([0,40,2]\) viewing rectangle. What does the shape of the graph indicate about the relationship between one's age and the number of annual physician visits? Use the \([\mathrm{TABLE}]\) or minimum function capability to find the coordinates of the minimum point on the graph of the function. What does this mean?
