Question

45pts help! What is the equation of the quadratic function represented by this table?

Answer 1

y=-1/4(x- - 2)^2+ 4

You can see it take shape by drawing it out. Then shift x left by 2 (-2) and up 4 (+4) . A trick for the slope is that by looking at .75 you know it has to be some fraction with a even denominator.
