If f(x) is an inverse of g(x),
when
f(x)=y
g(y)=x
aka
f(g(x))=x
g(f(x))=x
basically, the values should be swiched
example
f(x)=
(1,2)
(2,3)
(4,5)
then g(x)=
(2,1)
(3,2)
(5,4)
Find 8% of 1900.
0.08 * 1900 = 152
So 152 customers run every day.

Slope:-
Slope of perpendicular line:-
Passes through k(3,-3)
Equation in point slope form
- y-y1=m(x-x1)
- y+3=-5(x-3)
- y+3=-5x+15
- y=-5x+12
Check one by one
- 0=-5(-12)+12=60+12=72
- 2=-5(2)+12=-10+12=2
Yes option B is correct
