If a quadratic function has x-intercepts at (-7,0) and 10,0), where would the axis of symmetry be? Write your answer as an equation.

x = 1.5

Step-by-step explanation:

Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.

(-7 + 10) / 2

3/2

= 1.5

So, the axis of symmetry is at x = 1.5

expression #3 is not equivalent. the others are.

they disappear if your absent from to long. i found out that the hard way.

brainliest lol i just need one more brainliest.
