Question

The inverse of the function f(x) = one-half x plus 10 is shown. h(x) = 2x- What is the missing value?

Answer 1

Given: f(x) = x/2 + 10

To find: The inverse of f(x) and missing place?

Solution:

• Now we have given f(x) = x/2 + 10

• Let f(x) = y

                 y = x/2 + 10

                 2(y - 10) = x

• Now we have considered f(x) = y.

• So x = f^-1(y)

                 f^-1(y) = 2(y - 10)

                 f^-1(x) = 2(x - 10) = 2x - 20

Answer:

             So the missing place is 20 and inverse is 2x - 20 .
