Question

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? A. It is equal for both functions. B. It is 3 units higher for f(x) than g(x). C. It is 3 units lower for f(x) than g(x). D. It is 4 units lower for f(x) than g(x).

Answer 1

I can confirm that the answer above is correct because I just took the test and got it right.

Explanation:

Answer 2

g ( x ) maximum value = 8
f ( x ) maximum value = 5
g ( x ) max - f ( x ) max = 8 - 5 = 3
Answer:
C ) It is 3 units lower for f ( x ) than g ( x )
