Answer:
Step-by-step explanation:
Substitute 2 into x in the equation so f(x)= 5x2 -12 = -2 so it’s C = -2
Answer: C
<u>Step-by-step explanation:</u>
f(x) = 2x + 1 ⇒ 2x + 1
<u>- g(x) = -(x² - 7) </u>⇒ <u>-x² + 7 </u>
(f-g)(x) = -x² + 2x + 8
Answer:
For 3: A,D
For 4: I think A
Step-by-step explanation:
3: the reason is because as it approaches infinity, y is infinity
4. as c increases, y increases the same amount
