Answer 2

Answer:

$\left(f\:\circ \:g\right)\left(x\right)=\quad3x^2-13$

(3x² - 13)

Step-by-step explanation:

$\left(f\:\circ \:g\right) = f(g(x))$

f(x) = 3x + 2

g (x) = x² - 5

substitute values:

f ( g ( x ) )

{plug in "g(x)" as the x in f(x)}

3x + 2

3(x² - 5) + 2   {distribute 3 to x² and -5}

3x² - 15 + 2  {combine like terms}

3x² - 13

$\left(f\:\circ \:g\right)\left(x\right)=\quad3x^2-13$

(3x² - 13)

hope this helps!! :)
