We have the parent function:

y = x³ and we have to choose the correct answer to the question: which equation describes how is this function vertically stretched by a factor of 4.

y = x³ + 4 → The parent function is moved vertically 4 units up.

y = (x + 4) ³ → The parent function is moved horizontally 4 units left.

y = x^4 → This is a different function.

Answer:

C) y = 4 x³.
