Answer: y = $-\frac{4}{3}x^{2}$

<u>Step-by-step explanation:</u>

y = ax² ; where a represents the vertical stretch

a reflection across the x-axis is represented by making the a-value negative.

Answer:

$y=-\frac{4}{3}x^{2}$

Step-by-step explanation:

The given parabola is a parent function, that is, it's the simplest form of a parabola.

The first transformation is about a reflection across the x-axis, this means that we need to multiplied the squared factor by a negative signed, that is

$y=-x^{2}$

This represents a parabola reflected across the x-axis.

The second transformation is about a scale factor of 4/3, this means that the function has to be multiplied by this factor to obtain the transformation. The expression would be

$y=-\frac{4}{3}x^{2}$

Therefore, this final expression represents the function reflected across the x-axis and scaled by a factor of 4/3.
