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.
on the matrix gives![\left[\begin{array}{cc|c}5&5&5\\1&-\dfrac23&5\end{array}\right]\to\left[\begin{array}{cc|c}1&-\dfrac23&5\\5&5&5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D5%265%265%5C%5C1%26-%5Cdfrac23%265%5Cend%7Barray%7D%5Cright%5D%5Cto%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%26-%5Cdfrac23%265%5C%5C5%265%265%5Cend%7Barray%7D%5Cright%5D)
