The function values are f(1) = -3, f(-2) = -12, f(x + 4) = 3x + 6
The problem is incomplete. The complete problem is
Find the function value, if possible. (If an answer is undefined, enter UNDEFINED.) f(x) = 3x − 6
(a) f(1)
(b) f(−2)
(c) f(x + 4)
We have
(a) f(1) = 3 (1) - 6 = 3 - 6 = -3
(b) f(-2) = 3(-2) - 6 = -12
(c) f(x + 4) = 3(x + 4) - 6 = 3x + 6
So, the evaluations are f(1) = -3, f(-2) = -12, f(x + 4) = 3x + 6
