Question

If f(x) = x + 7 and g(x)=1/x , what is f(g(x)) ?

Answer 1

Answer:

f(g(x)) = $\frac{1}{x} + 7$

Step-by-step explanation:

If f(x) = x + 7 and g(x)=1/x

f(g(x)), plug in g(x) in f(x)

g(x) = 1/x

first we plug in 1/x for g(x)

f(g(x)) = $f(\frac{1}{x})$

Plug in 1/x for x in f(x)

f(x) = x + 7

f(g(x)) = $f(\frac{1}{x})$ = $\frac{1}{x} + 7$
