Question

if f(x)=5x, what is f^-1(x)

Answer 1

Step-by-step explanation:

For convinces sake lets say f(x) is y:

y

=

5

x

+

12

T

o find the inverse of the function, swap x and y and solve for y again.

x

=

5

y

+

12

Subtract 12 on both sides:

x

−

12

=

5

y

Divide by 5:

y

=

x

−

12

5

So

f

−

1

(

x

)

=

x

−

12

5
