Given the parent function:


y=x^3

If y is shifted right by 7 units, we obtain:


Option\text{ D: }y=(x-7)^3

If y is compressed horizontally by a factor of 7, we have:


Option\; E\colon y=(7x)^3=7^3x^3

If y is stretched vertically by the factor 7, we obtain:


\text{Option H: }y=7x^3

A shift downwards by 7 units gives:


\text{Option A: }y=x^3-7
