Nnesha (nnesha):

f(g(x)) means substitute x for g(x) function into f(x) $\huge\rm f(\color{ReD}{g(x)})=(\color{ReD}{x+5})^3$ here is an example find f(g(x) ) when f(x) = x and g(x)= 2x so you should substitute x for 2x into f(x) function $\large\rm f(\color{ReD}{g(x)})=\color{ReD}{x}~~~~~~~~~~~~~~f(\color{Red}{g(x)})=\color{Red}{2x}$

well f(g(x)) means f of g of x so we should replace x with the entire equation g(x) |dw:1442155749234:dw|
