If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (fog)(x)?

Step-by-step explanation:

We know that if f and g are functions, then the composite function of f and g is defined by :-

Given: If

Then,

Hence,

step-by-step explanation:

first, eliminate the parenthesis:

3

x

+

2

−

4

x

second, group like terms:

3

x

−

4

x

+

2

third, combine like terms:

(

3

−

4

)

x

+

2

→

−

1

x

+

2

→

−

x

+

2

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
