Which function has an inverse that is a function?

Answer:

<em><u>The answer is m(x) </u></em><em><u>= -7x =</u></em><em><u>A function will only have an inverse function if the function is one-to-one. If you graph the function out and it passes the horizontal line test, it is one-to-one. Only the function m(x) = -7x will have an inverse that is a function. The graph of y = m(x) is a linear function. Linear functions pass the horizontal line test (it's symmetric about the y-axis). The function does not have an inverse that is a function because the graph of b(x) is parabolic. It will fail the horizontal line test when you graph it out. The function does not have an inverse that is a function because the graph of d(x) is a horizontal line. A horizontal line fails the horizontal line test because it is a horizontal line. The function does not have an inverse that is a function because the graph of p(x) fails the horizontal line test (it's symmetric about the y-axis).</u></em>

The height of a cylinder is twice the radius of its base.
Ber [7]

Let x represent radius of circle.

We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be 2x.

Now we will use volume of cylinder formula to our given problem.

V=\pi r^2h, where,

r = Radius of base of cylinder,

h = Height of cylinder.

Upon substituting our given values, we will get:

V=\pi\cdot x^2\cdot 2x

V=2x^3\pi

Therefore, our required volume expression would be 2x^3\pi.
