Which function has a vertex on the y-axis? fx=x-22 fx=xx+2 fx=x-2x+2 fx=x+1x-2
Accepted Solution
A Write properties of function: vertex form: f{(x )} = (x - 2)^{2}vertex: (2,0)B Write properties of function: vertex form: f{(x )} = (x + 1)^{2} -1vertex: (-1,-1)C Write properties of function: vertex form: f{(x )} = x^{2} - 4vertex: (0,-4)D Write properties of function: vertex form: f{(x )} = (x - \dfrac{1}{2})^{2} - \dfrac{9}{4}vertex: (\dfrac{1}{2},- \dfrac{9}{4})
