Answer:
-64
Step-by-step explanation:
If
y=x^2
and the x represents -8
Your answer will be -64
By saying that x=(-8) all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it y=(-8)^2
When you plug in negative 8 to the second power into the calculator your answer will be -64

Answer:
Step-by-step explanation:
LOL The graph doesn’t match the y intercept :)
Anyway
If we have point (0,-3) we have a quadratic of
y=ax^2+bx-3 we are given points (-1,0) and (2,0) so
a-b-3=0 and 4a+2b-3=0
4a+2b-3+2(a-b-3)=0
4a+2b-3+2a-2b-6=0
6a-9=0
6a=9
a=1.5, since a-b=3
1.5-b=3
b=-1.5
y=1.5x^2-1.5x-3
