Answer:
Inverse function: 
Step-by-step explanation:
The inverse of a functon 
is the function 
such that 
.
In this problem, the function that we have to reverse is
In order to reverse the function, we do it in this way:
1) First, we isolate x and we write it as a function of y. Therefore:
2) Then, we exchange the names of the variables, so:
Therefore, the inverse function is
If I understand this question correctly, Diego will pay $1.12 because the 9 rounds the 1 up to a 2.
Subtract 4 from both sides. You'll get 8x = 28. Solving for x, x = 28/8 = 7/2
Answer:
y=3x-2
Step-by-step explanation:
you find the 3 (the slope) by seeing how much the y value grows
the -2 is the value of the y-intercept (more clear on a graph) but it's when the point is (0,__) so you subtract 3 from 1.
