1. Graph y = x^2 + 2x - 2. Identify (a) the vertex, (b) axis of symmetry, (c) x-intercepts, and (d) y-intercept.

Answer 1

This is a parabola which goes to + infinity as x increases in either direction.

The abscissa of the vertex is -2/2 = -1; you can compute the ordinate.

The axis of symmetry goes through the vertex.

The quadratic equation will give you the x intercepts and the y intercept is -2.
