Answer 1

Answer: OPTION 2. 39

Explanation:

g(x)=x²+3x-1 ⇔ Given

g(5)=(5)²+3(5)-1 ⇔ Plug the value of x in (5)

g(5)=25+15-1 ⇔ do all the operation (square, multiplication, etc.)

g(5)=40-1 ⇔ combine like term (first do the first two)

g(5)=39 ⇔ combine like term

Hope this helps!! :)

Answer 2

B

Explanation:

So we have:

`g(x)=x^2+3x-1`

To find g(5), substitute 5 for x:

`g(5)=(5)^2+3(5)-1`

Square and multiply:

`g(5)=25+15-1`

Add:

`g(5)=40-1`

Subtract:

`g(5)=39`

So, our answer is B :)
