Question

Functions 1 and 2 are shown:

Function 1: f(x) = −4x2 + 9

Function 2: a parabola that opens down the goes through points negative 2 comma 1, 0 comma 9, and 2 comma 1

Function 1 has a larger maximum.
Function 2 has a larger maximum.
Function 1 and Function 2 have the same maximum.
Function 1 does not have a maximum value.

Answer 1

they have the same maximum

Explanation:

Answer 2

They have the same maximum.

Explanation:

Function 1: y = 4x^2 is symmetrical about the y axis so its maximum value is when x = 0, which is 9.

Function 2: The graph passes through 0, 9 (given) and the x intercepts (-2,0) and (2, 0) are equidistant from the origin so it is also symmetrical about the y-axis and it's maximum is also 9.
