: Match each graph with the correct equation on the right.
This graph is a curve graph that starts at points(-1,20) the curve drops down to points (3, -4) and back up to points (6,20). I am not sure if these are right I just duplicated the graph to get the coordanance. The equations are:
a)y=-x^2+1
b)y=2x
c)y=x^2-4x
d)y=-x=1
e)y=-x^2+3x
f)y=x^2+1
g)y=x+1
h)y=2x^2
Thanks for your help.

Since the graph is opening upward, we know the leading coefficient is positive and we know its a quadratic since its a parabola. So lets try
Plug in (-1,20
not true. So thats not the equation
Lets try
Plug in (-1,20)

not true. So thats not the equation
Plug in (-1,20)

not true. So thats not the equation
It seems that none of these equations work. Double check your graph to see if you copied the coordinates down right.
