Answer:
It is the last one 1 5/24
Answer with Step-by-step explanation:
We are given that a function

a.We have to find the inverse of m.
Suppose, 




Replace x by y and y by x

Substitute 

b.When the inverse function of given function is 
Then , we get fog(x)=

When f and g are inverse to each other then fog(x)=Identity function.
c.If f(x)=x
It is self inverse function.
Answer:
y=3x+7
Step-by-step explanation:
y=mx+c
m=3 parallel lines have the same gradient
(-2,1)
(x,y)
y=mx+C
1=3x-2+c
1=-6+c
c=7
y=3x+7
