1) find the inverse function of f(x)=1/2x+3
2)use composition to verify that they are inverse relations?
3) f^ domain : range:
4) f^-1 domain : range:

 y = 1/2x + 3
change x and y

x = 1/2y + 3
now find the value of y and that is inverse function 

x - 3 =1/2 y
y = 2x- 6
 
f-(x) = 2x - 6


for both domain : ( - ∞ , + ∞ )

range f (x) : ( - ∞ , + ∞ )  - { 0 }
range f-(x) :( -∞ , +∞)

Hi i’m back at my moms now i cannot is a way you to come over and
