Task 1
Part 1. Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are inverses.
f(x)=x+a/b
g(x)=cx−d
Part 2. Show your work to prove that the inverse of f(x) is g(x).
Part 3. Show your work to evaluate g(f(x)).
Part 4. Graph your two functions on a coordinate plane. Include a table of values for each function. Include 5 values for each function. Graph the line y = x on the same graph.

Best ResponseYou've already chosen the best response.0yes you can use any value. I was asking which one of those is the right format for f(x)

Best ResponseYou've already chosen the best response.0I'm guessing you mean the top one? If that's the case, b = c and a = d.

Best ResponseYou've already chosen the best response.0ok what about 7 and 5

Best ResponseYou've already chosen the best response.0Actually that doesn't make sense because then you could just subtract a/b. Is just a in the numerator of the fraction?

Best ResponseYou've already chosen the best response.0yes so are there any specific numbers I have to put In because remember f(x) ad g(f) have to be inverses

Best ResponseYou've already chosen the best response.0tbh I'm kind of confused. I'm still stuck on what f(x) is supposed to be. The format makes a difference because of order of operations. Is it the top one I have drawn above, or the bottom?

Best ResponseYou've already chosen the best response.0\[f(x)=\frac{ x+7 }{ 5 }\]

Best ResponseYou've already chosen the best response.0Find f(g(x)) or g(f(x)). If you get x, they're inverses

Best ResponseYou've already chosen the best response.0https://www.desmos.com/calculator you can use that to graph. just use y= in front of the equation
