Which statement best predicts the changes to the graph of y = 3x^2 when ________ the coefficient of x^2 is changed to -1? III.A.2 The graph becomes narrower and shifts down 1 unit. The graph becomes narrower and opens downward rather than up. The graph becomes narrower and shifts 1 unit to the left. The graph becomes wider and opens downward rather than up. The graph becomes wider, shifts down 1 unit, and opens up rather than downward

Solution

This is the equation of a parabola and the value of y decrease as the coefficient of x² decreases since it is directly proportional to y

The correct answer will be B as the graph will become narrower due to decrease in the value of coefficient as well as the graph will become downward since the negative value of coefficient is replaced with positive value.

For ex:- if we put x=1 we will get y=-1(1)² = -1
