Which is not an equation of the line that passes through the points (1, 1) and (5, 5)?

Provide an example of a trigonometric function and describe how it is transformed from the standard trigonometric function f(x) = sin x, f(x) = cos x, or f(x) tan x using key features.

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=
