An easy way to do this is to plug in your answer choices in the correct variable places.
A - 1,5 so 3 (5) -2 = 13 // 8 (1) + 5 = 13
Therefore does 13 = 13? Yes
B. 3,9 so 3 (9) -2 = 25 // 8 (3) + 5 = 29
Therefore does 25 = 29? NO, so choice B is out
C.-4,9 so 3 (9) -2 = 25 // 8 (-4) + 5 = -27
Does 25 = -27? NO, so C is out
D. -2,3 so 3 (3 )-2 = 7 // 8 (-2) + 5 = -11
Does 7 = -11? NO, so D is out
YOUR ANSWER IS A
Answer:
D
Step-by-step explanation:
f(x) = 3x^2 - 2x + 5
f(-2) means that wherever you see an x on the right, you put in the value of -2 for the x.
f(-2) = 3(-2)^2 - 2(-2) + 5
f(-2) = 3(4) + 4 + 5
f(-2) = 12 + 9
f(-2) = 21
The answer is D
