If (f+g)(x) = 3x to the second power + 2x - 1 and g(x) = 2x - 2, what is f(x)?
o a 3x2+1
ob. 3x2-1
oc. 3x2+4
od. 3x2-4
o e. x2 -2

A. 3x²+1

Step-by-step explanation:

(f+g)(x)=f(x)+g(x)

given that

(f+g)(x)=3x²

g(x)=2x-2

f(x)=?

put in the values

3x²+2x-1=f(x)+2x-2

subtract 2x from both sides

3x²+2x-2x-1=f(x)+2x-2x-2

3x²-1=f(x)-2

add 2 on both sides

3x²-1+2=f(x)-2+2

f(x)=3x²+1

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
