Question 153036: What is the maximum value of q(x) = -2(x + 4)^2 + 23? @ The quadratic’s leading factor is negative (-2), so the curve opens “down” indicating it has a maximum. In the completing-the-square format, this ordinate apex value is the constant found at the end.
a. -32
b. 4
c. 23
d. There is no maximum value
