Answer:
They have the same maximum.
Step-by-step 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.
