basically the inverse is when you reflect the function across the identity line, y=x

basically to find the inverse of a function
flip switch all x and y and solve for y, then replace y with finverse

f(x)=7x-13
y=7x-13
switch
x=7y-13
solve for y
x+13=7y
(x+13)/7=y

finverse=(x+13)/7

3rd one
quantity of x plus 13 over 7
