The vertical stretch of 5 in the equation y = x is defined by .
Explanation:
The given equation is,
It can be written as,
The function is defined as .
If , then the function has a vertical stretch by a factor of S units.
If , then the function has a vertical shrink by a factor of S units.
Since we have to find the vertical stretch of 5 in the equation y = x.
The below figure shows the graph of y = x and .
