Question

Circle describes and correct each error Sketch the graph of the equationY=x^2+2x-1

Answer 1

y = x^2 + 2x -1

The vertex is at x = -1 and y = -2 so that is at the correct location

Check

Next check the the y intercept

Let x = 0

y = -1

The graph does not cross the y axis at -1 when x = 0

The graph drawn is too narrow
