[tex]f^{-1}(x)=\frac{x+13}{7}[/tex]
Step-by-step explanation:
Basically the inverse is when you reflect the function across the identity line, y = x . To find the inverse of a function, flip switch all x and y and solve for y, then replace y with [tex]f^{-1}[/tex]
f (x)= 7 x - 13
y = 7 x - 13
Swap x and y, we get
x = 7 y - 13
solve for y
x + 13 = 7 y
[tex]f^{-1}(x)=y=\frac{x+13}{7}[/tex]
