Use f(x) = 2 x and f-1(x) = 2x to solve the problems.

f^-1(f(x))= f(f^-1(x))

see the procedure

Step-by-step explanation:

we have

step 1

Find

substitute the variable x for the function f(x)

simplify

step 2

Find

substitute the variable x for the function f^-1(x)

simplify

step 3

Compare

therefore

---> is verified

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
