Question

.

Answer 1

F(19)= 5(19+4) - 6.. complete the rest

Answer 2

well, first, find the inverse of f(x) = 5(x+4) - 6
\(\bf f(x) =\color{red}{y} = 5(x+4) - 6\qquad inverse\implies x = 5(\color{red}{y}+4) - 6\)

solve for "y" in the inverse

Answer 3

once you get the inverse \(\bf f^{-1}(x)\) solved by "y", find \(\bf f^{-1}(19)\)
