For the function f(x) = x2 -12, find (f o f-1)(4) A. 0 B. 4 C. 10 D. 6

slega [8]

We actually don't need to do any computation. By definition, the inverse function $f^{-1}$ changes the role of input and output. So, if a function f maps x onto y, the inverse function maps y onto x.

You have to think like this: if the function makes a step further, the inverse function makes that same step back.

This means that the composition $f \circ f^{-1}$ is always the identity function $f(x) = x$ . In fact,

$(f\circ f^{-1})(x) = f(f^{-1}(x)) = x$

So, for every function, you have

$(f\circ f^{-1})(4) = f(f^{-1}(4)) = 4$

The height, h, of a falling object t seconds after it is dropped from a platform 300 feet above the ground is modeled by the fun

notka56 [123]

Average rate = [h(3) - h(0)]/(3 - 0)
h(3) = 300 - 16(3)^2 = 300 - 16(9) = 300 - 144 = 156
h(0) = 300 - 16(0)^2 = 300

average rate = (156 - 300)/3 = -144/3 = -48

Therefore, the object falls with an average rate of 48 ft/s during the first 3 seconds.

If this figure is a regular figure? How many degrees does each angle measure?

$\frac{(5 - 2) \times 180}{5} = \\$

$\frac{3 \times 18 \times 10}{5} = 3 \times 18 \times 2 = \\$

$54 \times 2 = 108$

Thus each angle has a measure of 108° degrees.
