Question

Given that f(x)=x^2 + x and g(x) = 3x + 1,
find the value f(g(4))

Answer 1

Answer:

110

Step-by-step explanation:

Given that $f(x)=x^2 + x$ and $g(x) = 3x + 1$ , find f(g(4))

f(g(4)) ==> you always start from the inside (g(4)).

$g(x) = 3x + 1$

$g(4) = 3(3) + 1$

$g(4) = 9 + 1$

$g(4) = 10$

$f(x)=x^2 + x$

$f(10)=10^2 + 10$

$f(10)=100 + 10$

$f(10)=110$

Final answer, 110.
