g(x) = ax^2+24
For the function g defined above, a is a constant and g(4)=8. What is the value of g(−4)?

8
\because g( 4)=8
Substituting into the given function g(x)= ax^2+24 establishes the following equation
8 = 4^2a+24
Solve the equation
1=2a+3
a=1
g(x) is determined as
g(x) = x^2+24
Substituting x=4 into the function gives
g(4)=(4)^2+24=8
A is correct choice
