Answer:
-15
Step-by-step explanation:
because you have to add 12 to -3
Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is
<span>x = a(y - k)^2 + h </span>
<span>There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. </span>
<span>Then look at what is added and compare it to h = -1. </span>
<span>For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).</span>
F(0)= 5 because 3(0) is the same as 0 and you add 5 so f(0)= 5
the answer to your question is -8 - 4x
