What is the axis of symmetry for a parabola with x-intercepts (-3, 0) and (7,0)?


Sagot :

Answer:

[tex]x = 2[/tex]

Step-by-step explanation:

Since the x intercepts both share zero as a y point. We can find the midpoint of the x coordinates to find the axis of symmetry.

[tex] - 3 + 7 = 4[/tex]

[tex] \frac{4}{2} = 2[/tex]

so the axis of symmetry is 2.
