The function f(x) = x2 is transformed to f(x) = −1.4x2. Which statement describes the effect(s) of the transformation on the graph of the original function?
A) The parabola is wider and reflected across the x-axis.
B) The parabola is wider and reflected across the y-axis.
C) The parabola is narrower and reflected across the x-axis.
D) The parabola is narrower and reflected across the y-axis.

C)The parabola is narrower and reflected across the x-axis.

Step-by-step explanation:

The original parabola has equation:

The transformed parabola has equation

How wide the graph is can be determined by the absolute value of the coefficient.

The smaller the absolute value of the coefficient, the wider the graph.

Since

The original graph is wider than the transformed graph.

Also the negative factor tells us there is a reflection in the x-axis.
