This is a parabola, meaning the equation is a quadratic, so it has 2 roots or x-intercepts, keeping in mind that vertex will lie half-way between those intercepts.
so what's the x-value halfway between -3 and 7? yeap, you guessed it, 2.
so the axis of symmetry for this vertical parabola will be at x = 2.
You have to find a common denominator first.
hey, wait a second... I saw you earlier, are you just putting all the questions on your math test here so you dont have to any of the work?
that's pretty smart.
