Question

Given fx ( ) = 2x 2 + 4 f 2 , determine ( ) f −1 and () .

Answer 1

Answer:

12 and 6

Step-by-step explanation:

The equation is not properly formatted presumably here is the format.

Given

$f(x) = 2x^2 + 4$

determine f(2) , and f(−1).

So we are expect to perform substitution operation and return an answers for values of x= 2 and x= -1

1. When x= 2 we have

$f(2) = 2*2^2 + 4\\\\f(2)= 2*4+4\\\\f(2)= 8+4\\\\f(2)= 12$

2. When x= -1 we have

$f(-1) = 2*-1^2 + 4\\\\ f(-1)= 2*1+4\\\\ f(-1)= 2+4\\\\ f(-1)= 6$
