Question

If g(x) = 3х + 1, evaluate g(-2).

Answer 1

Answer:

Step-by-step explanation:

g

(

b

2

+

)

=

2

−

b

 or  

g

(

Explanation:

In the notation  

g

(

x

)

you know that whatever is put in the parentheses is what replace for  

x

. In this situation, because it says  

g

(

b

2

+

1

)

, you replace every  

x

in the function with  

b

2

+

1

. You would then simplify the function further.

If  

g

(

x

)

=

3

−

x

5

+

x

,

then  

g

(

b

)

=

Answer 2

Answer:

5

Step-by-step explanation:

g(x) = 3х + 1, evaluate g(-2).

g (-2)= 3 × (-2) + 1

= -6 + 1 =5

all u have to do is substitute (-2) where there is an x
