Answer 4

f(x) = one eighth (x − 3)2 + 4

Answer 5

Thanks, but I want to learn how to solve these, plus the last number has to be a 3 according to the multiple-choice answers given.

Answer 6

And this is a negative parabola, meaning it opens downward, becuase the focus is below the directrix. SO..

Answer 7

y = 4px^2 and p = -1/2
