Which of the following equations is of a parabola with a vertex at (3, 0)? y = (x - 3)2 y = (x + 3)2 y = x2 - 3 y = x2 + 3

That would be y = (x - 3)^2  Answer

The answer is A. y=(x-3)^2

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
