25 POINTS PLZ HELP ASAP!!!<br><br> Match the functions with their inverse functions.

antoniya [11.8K]

To calculate the inverse isolate x on one side and switch x with y on both sides

1)
y=(2x-3)/5
5y=2x-3
5y+3=2x
(5y+3)/2=x
-> f(x)=(5x+3)/2

2)
y=(x+8)/2
2y=x+8
2y-8=x
-> f(x)=2x-8

3)
y=(x+2)/7
7y=x+2
7y-2=x
-> f(x)=7x-2

4)
y=(1-2x)/x
y=(1/x)-2
y+2=1/x
x=1/(y+2)
-> f(x)=1/(x+2)
