Answer:
See explanation
Step-by-step explanation:
Given the function f(x) for which

If you want to plot the corresponding points for the inverse of the function f(x), change
into
:

switch x and y

and then change
into
You get

Now plot these points on the coordinate plane (see attached diagram).
Answer:
60
Step-by-step explanation:
45 x 60/45 = 2700/45
2700/45 = 60
Divide both sides by -0.7 to get rid of that pesky thing in the front
0.3x-0.8=6.4
add 0.8 to both sides
0.3x=7.2
divide both sides by 0.3
x=24
