Question

Determine the quadratic equation in standard form of a parabola with a zero at x=5 and vertex ar (-3, 32). start with factored form

a)find the other zero

b) create your factored form equation

c) create your standard form equation ​

Answer 1

see image...

start with Graphing Form: y = a(x-h)²+ k

knowing that h is the x value (negative of it) of the vertex , and k is the y value of the vertex

Graphing Form Equation: y = a(x+3)²+32

you are also given that when the x value is 5 the y value has to be 0

0 = a(4)^2 + 32

a has to be - 1/2
