Answer:
4x^2 + x
Step-by-step explanation:
just multiply x to each of the terms.
Step-by-step explanation:
Inflection points are where a function changes concavity (the second derivative changes signs). At x = 4, f"(x) goes from negative to positive, so that's an inflection point. However, at x = 8, we don't know if f"(x) changes signs or not. So we can't say that that's an inflection point.
Answer:
h(-6) = -22
Step-by-step explanation:
h(n) = 3n - 4
h(-6)= 3(-6) - 4
= -18 - 4
= -22
Answer:
B) 116°
Step-by-step explanation:
y=180-54-64=62
x=180-62-64=54
62+54=116
