Maria graphs the following 3 equations: y = 34, y = 3x2, and y = 6x.

She says that the graph of y = 3X will eventually surpass the graph of y = 6x, but not the
graph of y = 3x2 because the graph of y = 3x2 has already surpassed the graph of y=
3X.
Is Maria correct? Why or why not?

Answer:

Maria is not correct.

The graph of y = 3x grows at an increasingly increasing rate, but the graph of y = 3x2 grows at a constantly increasing rate.

Therefore, the graph of y = 3x will eventually surpass the graph of y = 3x2.

Explanation:

Yes, graphs of exponential equations grow at an increasingly increasing rate.

Graph with X-axis labeled by ones from negative 2 to 5 and Y-axis labeled by 10s from negative 10 to 70. 2 equations are graphed in different colors. Equation 1 is y = 3 superscript x and is a curve opening up and to the left, starting near the X-axis at left and continuing up and to the right, getting steeper as it goes right. Equation 2 is y = 3 x squared, a parabola opening upward with vertex at (0, 0).
