For this case we have:
Let two functions, f (x) and g (x), then the composite function of f with g is [tex](gof) (x) = g [f (x)][/tex]
Let:
[tex]g (x) = 5x-3\\h (x) = \sqrt x[/tex]
We want to find [tex](g_ {0} h) (x)[/tex]
[tex](g_ {0} h) (x) = g [h (x)] = g (\sqrt x) = 5 \sqrt x -3\\(g_ {0} h) (4) = 5 \sqrt (4) -3 = 5 * 2-3 = 7[/tex]
Answer:
7
