Let's say the function for the discount is f and the function for the coupon is g
f(x)= 0.1x
g(x)= x-150
If you want to the the discount then the coupon, your composition function would look like this:
f(g(x))=0.1(x-150)
Hope this helps!
Answer:
A function of the form 
, where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
Step-by-step explanation:
A linear function is one in which the 
value of the function varies linearly with 'x'. When we plot a linear function on a graph, the resulting curve is always a straight line with the slope of the line being constant.
A linear function is of the form:
, where, 'm' and 'b' are real numbers.
The degree or the highest exponent of 'x' in a linear function is always equal to 1.
Therefore, a function of the form , where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
