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?
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).

Answer 1

Answer 2

x g(x) f(x)
0 0 0
1 4 1
^ ^ compare those two

Answer 3

ok so
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).

so I'm not gonna give answers.
when x = 1
g(x) = 4
and f(x) = 1
what's the difference?

Answer 5

ok

Answer 6

the difference is 1

Answer 7

? difference between g(x) = 4
and f(x) = 1
?

I've gtg. byebye

Answer 8

hmmm have you covered quadratics yet?

Answer 9

no

Answer 10

well... you may want to cover that first .. ... or make a table for f(x) to find its maximum point
and then compare with g(x)'s maximum point
