Answer:
D. Graph A
Explanation:
First, notice the function can be factored easily:
![y=x^2+10x+16 =(x+8)(x+2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/uy239jiuukion09wir7p1i7rkd3g5xpozl.png)
So we can see that the function hits the y-axis at 2 points:
(-8,0) and (-2,0).
Which of the graphs in the picture show a parabola that hits the y-axis at those points? Graph A is the only option.
So the answer is D. Graph A
