Answer:
12
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x)
f(x) + g(x) = x + 2 + x² - 2 = x² + x
To evaluate (f + g)(- 4) substitute x = - 4 into f(x) + g(x)
(f + g)(- 4) = (- 4)² + (- 4) = 16 - 4 = 12
Answer:
It is an enlargement because the shape increased in size.
Step-by-step explanation:
-1 is less than 0, so you use the first equation:
3(-1) +2 = -3+2 = -1
f(-1) = -1
For 0 use the 2nd equation:
3(0) + 4 = 0+4 = 4
f(0) = 4
For 2 use the 2nd equation:
3(2) + 4 = 6+4 = 10
f(2) = 10
The correct answer is 43. hope i helped:)
