Answer:
f^-1(x) = 4x-3
Step-by-step explanation:
f(x) = (x+3)/4
y = (x+3)/4
Exchange x and y
x = (y+3)/4
Solve for y
4x = y+3
Subtract 3
4x-3 = y
The inverse
f^-1(x) = 4x-3
Answer:
Unit rates are ratios that are used to compare different quantities
Step-by-step explanation:
It really depends on what kind of unit rate you're answering. So let's say that you go to the grocery store, and potatoes are $5.50 for 5. You would divide 5.50 by 5 to get the answer $1.10. Hope this helps!
If you divide x by y you get 4.5.
y = [<u>4.5</u>]x
