Pedro has created the function f(x) = the quantity of 4x minus 3, divided by 2 to represent the number of assignments he has completed, where x represents the number of weeks in the course. Pedro discovers that, using the inverse function to solve for x = 30, he can predict when he will have 30 assignments completed. Explain to Pedro how to accomplish this, using complete sentences.

f(x) = $\frac{ 4x-3 }{ 2 }$ Is that right?

Ok so I am going to assume that is right because I do not want to wait for you to respond. SO I will just run you through the steps: 1) Make f(x) = y, then switch x and y: x = (4y - 3)/2 2) Now solve for y: * 2 on both sides 2x = 4y -3 +3 on both sides 2x + 3 = 4y /4 on both sides y = (2x+3)/4 3) Now plug in 30 to find when he will have completed 30 assignments: y = (2(30) + 3)/4 y = (60+3)/4 y = 63/4 y = 15.75 Weeks Hope this helps, please award me a medal - and fan.
