The quadratic functions f(x) and g(x) are described as follows: f(x) = −8x^2 + 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.

well, we know that x^2 is always positive (or 0) so -8x^2 is always negative, or 0. the maximum value of -8x^2 is 0, so the maximum value of -8x^2 + 7 is...?

  • anonymous
8?
Vocaloid
  • Vocaloid
not quite... -8x^2 has a maximum value of 0 so if we add it to 7, what's our new maximum value?

7?

any ideas on the maximum value of g(x)?

0 is smallest and 6 is the largest.
Vocaloid
  • Vocaloid
so the maximum is...?
anonymous
  • anonymous
F(x)?
Vocaloid
  • Vocaloid
maximum means highest value so the maximum value of g(x) = ?
anonymous
  • anonymous
6?
Vocaloid
  • Vocaloid
right. now compare the maximum value of f(x) and the maximum value of g(x), which one is higher?
anonymous
  • anonymous
F(x) So the answer would be B?
Vocaloid
  • Vocaloid
yes ^ ^
