Answer:

f(x) = 4 for the values 2 and -2.

Step-by-step explanation:

Given

y = { x+6      x < -2

       x²        -2 ≤ x ≤ 3

      3x+1      x > 3 }

To determine

For which x-values is f(x) = 4

It is clear that:

The portion of the function f(x) = x² has the interval  -2 ≤ x ≤ 3

Now, if we enter x = 2 or x = -2 in f(x) = x² from the interval -2 ≤ x ≤ 3 we get the output 4.

i.e.

at x = -2,

f(-2) = (-2)² = 4

also

at x = 2,

f(2) = (2)² = 4

Therefore, f(x) = 4 for the values 2 and -2.
