Answer: True
Step-by-step explanation:
If a function is linear, it only goes in one direction, which means it can only intercept the x-axis one time.
Answer:
n=20
Step-by-step explanation:

Answer:
D=(-infinity, +infinity)
R=(-infinity, 4]
Step-by-step explanation:
I think that 2 is an exponent so you function is f(x)=-3(x-5)^2+4
So if this is the case this is a parabola open down when a vertex of (5,4).
Visualize or draw a rough picture of that because that is all you need to answer this question.
The domain for a parabola function is always all real numbers (do notice I said parabola function).
The range for this parabola is (-infinity, 4] since open down and the highest point has y value 4.
The answer would be A because you would take all of your answers and 1 by 1 multiply it by0.35 and it will give you the answer of $330.43
