Answer:
Step-by-step explanation:
Parent function has been given as,
f(x) = x²
If the parent function is reflected across x-axis,
g(x) = -f(x)
= -x²
Further this function is vertically stretched by 2 units then the new function will be,
e(x) = -2x²
Therefore, parent function 'f' is reflected across x-axis and vertically stretched by scale factor of 2.
