Answer:
Step-by-step explanation:
We are given zeros as x=-4, x=-2
so, we can set up function as
Vertex is at (-1,3)
It means that graph passes through point (-1,3)
so, we can plug x=-1 and f(x)=3
and then we can solve for 'a'
we get
now, we can plug it back
and we get
now, we can simplify it
2 * 2 and 3/4.
2 and 3/4 = (4*2 + 3) / 4 = (8 + 3) / 4 = 11 / 4
2 * 11/4 = 22 / 4 = 5 and 2/4
= 5 and 2/4 or 5 and 1/2 or 5.5
Hope this helps.
