Chapter 2: Problem 21

Determine whether each function is even, odd, or neither. $$h(x)=x^{2}-x^{4}$$

Short Answer

Expert verified
The function \(h(x) = x^{2} - x^{4}\) is an even function.

Step by step solution

01

Identifying the Function

The function given is \(h(x) = x^{2} - x^{4}\). The goal is to determine whether this function is even, odd, or neither.
02

Substitute -x for x

Substitute -x for x in the function \(h(x)\) to establish whether the function is even or odd. In the case of an even function, the result will be equal to \(h(x)\) (i.e. \(h(-x) = h(x)\)), and for an odd function, it'll be equal to \(-h(x)\) (i.e. \(h(-x) = -h(x)\)). Thus, when -x is substituted into the function \(h(x)\), it yields \(h(-x) = (-x)^{2} - (-x)^{4} = x^{2} - x^{4}\).
03

Comparing the original function to h(-x)

Now, it can be observed that the result of substituting -x for x (\(h(-x) = x^{2} - x^{4}\)) is identically equal to the original function \(h(x) = x^{2} - x^{4}\), which satisfies the condition of an even function (i.e., \(h(-x) = h(x)\)). The function does not meet the criteria of an odd function since \(h(-x) \neq -h(x)\).

write the standard form of the equation of the circle with the given center and radius. $$ \text { Center }(-3,-1), r=\sqrt{3} $$

determine whether each statement makes sense or does not make sense, and explain your reasoning. A tangent line to a circle is a line that intersects the circle at exactly one point. The tangent line is perpendicular to the radius of the circle at this point of contact. Write an equation in point-slope form for the line tangent to the circle whose equation is \(x^{2}+y^{2}=25\) at the point \((3,-4)\)

complete the square and write the equation in standard form. Then give the center and radius of each circle and graph the equation. $$ x^{2}+y^{2}-10 x-6 y-30=0 $$

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. $$ g(x)=x^{\frac{2}{3}} $$

give the center and radius of the circle described by the equation and graph each equation. Use the graph to identify the relation's domain and range. $$ x^{2}+(y-2)^{2}=4 $$
