If I remember correctly this is how you solve it.
f(x)=8x+6
f(-1)=8(-1)+6
f(-1)=-8+6
f(-1)= -2
Vertex form formula: y = a(x-h)^2 +k, with vertex (h,k)
There are multiple ways to find the vertex. One way is to find the roots and then find the x value exactly in between them, because this parabola is symmetrical.
0 = (x - 3)(x + 2), so x = 3 and -2. The point directly in the middle is x = 1/2 = h
To find the y value of the vertex, plug in 1/2 to the equation.
(1/2)^2 - 2(1/2) + 5 = 4.25 = k
y = (x - 0.5)^2 + 4.25
Answer:
Negative
Step-by-step explanation:
It going down starting from the left to right . Positive would be the other way around and zero would be side to side while undefined would be an up and down line .
