Q6

The function `y =x^3`

has been vertidcally stretched by a factor of 5, horizontally compressed by a factor of `\frac{1}{2}`

, horizontally translated 21 units to the right, and vertically translated 4 units up.

a) Write the equation of the transformed function.

b) The point `(1, 1)`

is on the parent function. Determine the new coordinates of the transformed function.
