<font face="Times New Roman" size="+2">


*[tex \LARGE g\,\circ\,f] is the same thing as *[tex \LARGE g\left(f(x)\right)] which is the same thing as *[tex \LARGE 2\left(f(x)\right)\ +\ 1] which is the same as *[tex \LARGE 2(5x)\ +\ 1] or *[tex \LARGE 10x\ +\ 1].


To find *[tex \LARGE \left(g\,\circ\,f\right)(-1)], substitute -1 for the variable and do the indicated arithmetic.
