HI!!!

OpenStudy (anonymous):

hi

OpenStudy (misty1212):

\[f(x)=\frac{1}{3}x+5\] find \[f^{-1}(3)\]?

OpenStudy (misty1212):

this really means "solve for x"\[\frac{1}{3}x+5=3\]

OpenStudy (anonymous):

idk @misty1212

OpenStudy (misty1212):

takes two steps yo\[\frac{1}{3}x+5=3\] subtract \(5\)\[\frac{1}{3}x=-2\] multiply by \(3\) \[x=-6\]
