HELP PLEASE DOUBLE CHECK MY ANSWER!!!
The quadratic functions f(x) and g(x) are described as follows:
f(x) = −8x2 + 7
x g(x)
0 0
1 2
2 6
3 2
4 0
Which of the following statements best compares the maximum value of the 2 functions?
It is the same for both functions.
f(x) has a greater maximum value than g(x).
g(x) has a greater maximum value than f(x).
The maximum values cannot be determined.
I chose A is that correct?

Best ResponseYou've already chosen the best response.1not quite, let's take a look at f(x) f(x) = −8x2 + 7 what is the biggest possible value of f(x)?

Best ResponseYou've already chosen the best response.1not quite, the biggest possible value of f(x) occurs when x = 0 what is the value of f(x) when x = 0?

Best ResponseYou've already chosen the best response.1f(x) = 8x^2 + 7 what is f(x) when x = 0?

Best ResponseYou've already chosen the best response.1substitute 0 for x in the equation... f(x) = 8x^2 + 7 = 8(0)^2 + 7 = ?

Best ResponseYou've already chosen the best response.1right, so the maximum value of f(x) is 7 now look at g(x). what is the maximum value of g(x)?
