Question

For each quadratic relation, determine the y-intercept and the axis of symmetry.

y=x(by the power of 2)+2

Answer 1

Someone please help?

Answer 2

The formula for a quadratic equation is y = (x - h)^2 + k. k is the y-intercept, and h is the horizontal shift. Since k in this problem is 2, the vertical shift is 2. The parent function, y = x^2, with a y-intercept of 0, has been shifted up 2 units, so the y-intercept is 2.

In this problem, h is 0, just leaving x^2. Since h is 0, there has been no horizontal shift, so the axis of symmetry is x = 0.
