Please help, I will give a medal. Functions f(x) and g(x) are described as follows: f(x) = -4x2 + 5 x g(x) 0 0 1 4 2 8 3 4 4 0 Which statement best compares the maximum value of the two functions? (4 points) It is equal for both functions. It is 3 units higher for f(x) than g(x). It is 3 units lower for f(x) than g(x). It is 4 units lower for f(x) than g(x).

What is the maximum value for f(x)?

Uhm.. I don't really know.

What happens if you have f(0)?

Nothing?

OpenStudy (astrophysics):

\[f(0) = -4(0)^2 +5 \implies f(0) = 5\] this is your maximum value

So since we know that, what can we say about g(x)?

OpenStudy (astrophysics):

Max value for f(x) = 5, look at your table of values and see g(x), what's the maximum value for that?

8?

Yeah, so what's your answer then?
