Answer:

Step-by-step exThis is a way to express finding the inverse function of  

f

(

x

)

=

x

2

16

Explanation:

First, write the function as  

y

=

x

2

16

.

Next, switch the  

y

and  

x

positions.

x

=

y

2

16

Solve for  

y

in terms of  

x

x

+

16

=

y

2

y

=

x

+

16

The inverse function should be  

f

1

(

x

)

=

x

+

16

put the numbers vertical

f(x) = 3x^2 + 16 Find f(-1)

3(-1)^2 +16
3(1) + 16
3 + 16
