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.
