Practice problem
Let ggg be the inverse of the function f(x)=15−4xf(x) = \frac{1}{5 - \frac{4}{x}}f(x)=5−x41. What is g(x)g(x)g(x)?
g(x)=45+1xg(x) = \frac{4}{5+\frac{1}{x}}g(x)=5+x14
g(x)=15+4xg(x) = \frac{1}{5+\frac{4}{x}}g(x)=5+x41
g(x)=15−4xg(x) = \frac{1}{5-\frac{4}{x}}g(x)=5−x41
g(x)=45−1xg(x) = \frac{4}{5-\frac{1}{x}}g(x)=5−x14
g(x)g(x)g(x) does not exist.
Type a concept, like “slope” or “photosynthesis”.
