Function f and function g are inverses of one another. What is f(g(t)) equal to?

a_sh-v [17]

Hello from MrBillDoesMath!

Answer: f(g(t)) = t

Discussion:

A function and its inverse "undo" each other. Suppose that

f(t) = t^2 and g(t) = t^ (1/2)

Then

A B C

g(f(t)) = g (t^2) = (t^2) ^ (1/2) = t

A: substitute the definition of f(t), that is t^2, in the equation

B: g(t) takes the square root if its argument

C: The square root of a squared item is the item itself.

Answer:

C 7ft/yr

Step-by-step explanation:

The given points are not all on the same line, so the average will vary depending on the interval of interest.

Over the interval [1, 11] years, the average rate of change of height is ...

change in height / change in years = (80 -10)/(11 -1) = 70/10 = 7 . . . ft/yr

On the interval [11, 15] years, the average rate of change is ...

(105 -80)/(15 -11) = 25/4 = 6.25 . . . ft/yr

Even on this interval, the closest answer choice is C.
