Question

The vertex of a parabola is (3,2). A second point on the parabola is (1,5). Which of the following points is also on the graph?

Answer 1

well we no the axis of symmetry on this parabola is x=3 since the vertex lies on the axis of symmetry. Due to this symmetry we can find the point reflected over x=3 by counting how far (1,5) is which is 2 units to the left of x=3. Then we move right 2 units from x=3 to get the (5,5) and since its just reflected, the y-value will be the same

Answer 2

so the answer is (5,5) correct?

Answer 3

yes

Answer 4

perfect thanks
