Question 1128838
------
A quadratic function has a minimum of -8 and an x-intercept of -5. Its axis of symmetry is x=-3. Find the y-intercept of this quadratic function.
------


The other x-intercept is  -1.


{{{y=a(x+5)(x+1)}}}


point (-3, -8) was described.


{{{a(-3+5)(-3+1)=-8}}}

{{{a(2)(-2)=-8}}}

{{{a(-4)=-8}}}

{{{a=2}}}



{{{highlight(y=2(x+5)(x+1))}}}


Find y-intercept:

{{{y=2(5)(1)}}}
