Answer:
D
Step-by-step explanation:
Here, we want to select which of the options that could actually be the inverse of function g
The function that could actually be an inverse is that function in which we have a reversal of values
What we mean in this case is that the x values take up the f(x) values while the f(x) values take up the x values
With respect to this question, the option that fits this description is;
Option D
The answer is y=3x.
y=21, x=7
y=mx (m is the variable for slope)
21=m(7)
m=21/7
m=3
The first equation uses the first and second coupons. the coupon (1-y)40 will take y% off of the dress pants so the answer is 40(1-y)
