Question 1163930
<br>
With x-intercepts at -1 and 3, the equation is of the form<br>
{{{y = a(x-(-1))(x-3)}}}<br>
or<br>
{{{y = a(x+1)(x-3)}}}<br>
Plug in the coordinates of the given point (1,-8) to determine the value of the coefficient a:<br>
{{{-8 = a(1+1)(1-3)}}}<br>
You can finish from there....<br>
