How do you find the standard form of the equation of the parabola with a vertex of (-1,4) and x intercepts of (-3,0) and (1,0)?
Please see the explanation.
If the x intercepts are
To find the value of k, substitute -1 for x and 4 for y:
Use the F.O.I.L. method to multiply the binomials:
Distribute the -1:
This is standard form.
