Question

If f(x) = x+3 and g(x) = x2, then fog(x)​

Answer 1

Answer:

Step-by-step explanation:

f(x) = x + 3

put g(x) in x which is $x^{2}$

fog(x) = f(g(x))  

fog(x) = ($x^{2}$) + 3

fog(x) = $x^{2}$ + 3

Answer 2

Answer:

3x² - 2

Step-by-step explanation:

f(x) = 3x - 2

g(x) = x²

fog (x) = f [g(x)]

= f(x²)

= 3(x²) - 2

fog (x) = 3x² - 2
