Step-by-step explanation:
15% of 30 is 4.5
Answer:5
Step-by-step explanation:5/3 x 3/1= 15/3= 5
For this case we have that the main function is given by:

We apply the following transformation:
Vertical displacements:
Assume k> 0
To graph y = f (x) - k, move the graph k units down.
For k = 3 we have:

Answer:
when the function is changed to f (x) - 3 the change that will occur is:
Vertical displacement 3 units down.
b is decreased by 25% which means there will be (-ve) sign.
