Mathematically, when you calculate the inverse function (f-1(x)), you’re switching the “inputs” (x) and the “outputs” (f(x)) and then re-solving the equation. So, you’d start with something like:
x = 3*f-1(x) + 3
x - 3 = 3*f-1(x)
(x - 3)/3 = f-1(x)
Your inverse formula would be (x - 3)/3. Hope this helps! (Hopefully Brainly doesn’t mess up the text format.)
Answer:
Shandra would pay $27.50 for 5 slices
Cost = 20+1.50x
Step-by-step explanation:
Given

per slice
Solving (a): Cost of 5 slices
Represent the total price with y and the number of slice with x.
So, we have:

This gives:

In this case: x = 5.
So, we have:



<em>Shandra would pay $27.50 for 5 slices</em>
<em></em>
Solving (b): Cost of x slices
This has been solved in (a).


Hence, the cost of x slices is 20+1.50x
