HEL Which of the following equations has an axis of symmetry with the equation x=1.5?
A. y=2x2−6x−1
B. y=2x2−3x+1
C. y=x2+6x−3
D. y=2x2+3x+2

Step-by-step explanation:

The axis of symmetry is the line that is smack dab in the middle of the shape. The only way you can do this is if you graph all 4 equations, and see which one has an axis of symmetry of 1.5. The picture below is showing all of the equations and their graphs color-coded. The black dotted line is the axis of symmetry a.k.a. x=1.5

As you can see, the axis of symmetry goes perfectly through only equation A, making A the answer.
