1) the roots of a parabola are 5 and -7. what is the equation of the parabola?


<pre>
The equation of the parabola is

y = (x-5)*(x-(-7)),   or, which is the same,

y = (x-5)*(x+7)
</pre>


2) what is the axis of symmetry for the parabola y=-1/16(x+4)^2-7?


<pre>
The axis of symmetry for this parabola is vertical line x = -4.
