Select the correct answer. What are the factors of this quadratic function? the graph of a quadratic function with a maximum value at the point (3,4) and zeros at 1 and 5 A. (x − 1) and (x − 5) B. (x + 1) and (x + 5) C. (x − 1) and (x + 5) D. (x + 1) and (x − 5)

Step-by-step explanation:

If the zeros of the quadratic are 1 and 5, that means that that's where the graph goes through the x axis.  ON the x-axis, the y value is 0.  Hence, the reason they are called "zeros".  

If x = 1 is a zero, then x - 1 = 0 is a factor.

If x = 5 is a zero, then x - 5 = 0 is a factor. Choice A is the one you want.
