Question

Which quadratic function is represented by the graph?

O y=0.5(x + 2)2 + 4
O y=0.5(x + 3)2 -0.5
O y=0.5(x - 3)2 -0.5
O y=0.5(x - 2)2 + 4

Answer 1

\begin{bmatrix}Oy=0\\ 0.5\left(x+2\right)\cdot \:2+4Oy=0\\ 0.5\left(x+3\right)\cdot \:2-0.5Oy=0\\ 0.5\left(x-3\right)\cdot \:2-0.5Oy=0.5\left(x-2\right)\cdot \:2+4\end{bmatrix}
