Correct Answer

D

Explanation

If we have two graphs, y = px² + q and y = 2x² - 1, we can compare the equations to identify any similarities or differences.Comparing the equations, we can see that both equations are in the form of y = ax² + b, where a and b are constants.For the first equation, y = px² + q, the coefficient of x² is p, and the constant term is q.For the second equation, y = 2x² - 1, the coefficient of x² is 2, and the constant term is -1.Therefore, the two graphs have different coefficients for the x² term and different constant terms. This means that the graphs will have different shapes and positions on the coordinate plane.To analyze the graphs further, we would need specific values for p and q in the first equation. Without those values, we cannot determine the exact relationship between the two graphs.
