Question

Which equation describes how the parent function y=x^3, is vertically streched by a factor of 4

Answer 1

`y=4x^(3)`

Explanation:

It is known that,

'Vertical stretch, stretches the function up and down towards the y-axis'.

The general form of vertical stretch is given by 'kf(x)', where k>1 is the factor by which function is stretched.

As, we have the function
`y=x^(3)` which is stretched by a factor of 4.

Thus, the new function will be
`y=4x^(3)`.

Hence, the equation for the vertical stretch is
`y=4x^(3)`.
