Question

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

Answer 1

Answer:

$y=4x^{3}$

Step-by-step 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 $y=4x^{3}$.
