Solution:
The Preimage function is , F(x)=x
Consider a point (a,b) on the function, F(x)=x. it means
b=a(1) satisfies the function.
Now the function F(x)=x is vertically stretched by 5 units.It means
x=a , y= b+5
x=a, b=y5
So, putting the value of a and b in equation (1).
y5=x
y= x + 5 is vertical stretch of y= x by 5 units.
