# Let f(x) = 2x-3 and g(x) = 4x, find (fog)(x)

Let $f\left(x\right)=2x-3\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}g\left(x\right)=4x,f\in d\left(f\cdot g\right)\left(x\right)$

$\left(f\cdot g\right)\left(x\right)=f\left(g\left(x\right)\right)=2g\left(x\right)-3=2\left(4x\right)-3=8x-3.$
