Question

I WILL MEDAL/FAN PLEASE, HELP ME.
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).

Answer 1

\[f(x)=\frac{ x+a }{ b }\]

Answer 2

Answer 4

so is

f(x)=x+a over b
ok so look at the inverse... swap x and y

x=y+a over b


can you make y the subject...?
ok... multiply both sides by b

bx=y+a


now you should be able to make y the subject
subtract a from both sides
well its subtract..
y = bx - a

now compare it to the inverse you are given

y = cx - d

what can you say about b, c and a and d..?
it requires you to swap x and y and then make y the subject...

so all you need to do, from the way I see it... is to find the inverse of f(x)

compare it to g(x) and make the conclusion c = b and a = d

then pick numbers for a and b using the conclusion you will also have c and d

whaaaaattt?
