Use f(x) = 5 x and f-1(x) = 2x to solve the problems.

f(2)=

fl(1) =

f11f2) =

f(2)= 5

f^-1(1)=2

f^-1(f(2))= 10

Step-by-step explanation:

first we need to find f(2), plug in 2 for x  in f(x)

To find f^-1(1) , we plug in 1 for x in f inverse

now we find f^-1(f(2))

we know f(2)= 10

so we find f^-1(10)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

a. is correct
