Which of the following is the graph of the quadratic function y - x? +10x+16 ?
a. graph c
b. graph b
c. graph a
d. graph d

Find the vertex:

Determine if the parabola will open up or down:

Since the value of a is positive, the parabola will open upwards

Find the x and y intercepts:

Factor to find the x intercepts

(x+8)(x+2)

x + 8 = 0

x = -8

x + 2 = 0

x = -2

x intercepts:

x = -2

x = -8

Find the y intercept

Hence, C. Graph A best represents the quadratic function

answer: do we write it
