Answer:
A reflection in the x-axis and a vertical stretch by a factor of ½.
Step-by-step explanation:
The parent function is f(x).
The transformed function is
[tex]g(x) = - f(2x)[/tex]
The negative sign means a reflection in the x-axis.
The 2 multiplying inside means a horizontal stretch by a factor of
[tex] \frac{1}{2} [/tex]
Therefore the transformation, is a reflection in the x-axis and a vertical stretch by a factor of ½.
