True or FalseThe cube root function is odd and is decreasing on the interval .
A rectangle is inscribed in a semicircle of radius . See the figure. Let be the point in quadrant I that is vertex of the rectangle and is on the circle.
Part (a): Express the area A of the rectangle as a function of x.
Part (b): Express the perimeter pof the rectangle as a function of x.
Part (c): Graph . For what value of xis Alargest?
Part (d): Graph . For what value of xis plargest?
In Problems 7–18, match each graph to one of the following functions:

A right triangle has one vertex on the graph of at , another at the origin, and the third on the positive y-axis at , as shown in the figure. Express the area Aof the triangle as a function of x.
In Problems 33– 44, determine algebraically whether each function is even, odd, or neither.
