Step-by-step explanation:
It is known that,
<em>'Vertical stretch, stretches the function up and down towards the y-axis'.</em>
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 which is stretched by a factor of 4.
Thus, the new function will be .
Hence, the equation for the vertical stretch is .
