The graph of y=3x^2+2 is a parabola that opens upwards, so the graph is wider vertically.
A horizontal stretch would make the graph of y=3x^2+2 wider horizontally. This would involve a coefficient greater than 1 being multiplied by the x^2 term.
Therefore, the graph of y=4x^2+2 is wider than the graph of y=3x^2+2.
which of the following has a graph that is wider than the graph of y=3x^2+2
