Question

if f(x) = 3x-2 and g(x)= x^2 + 1 find (f + g) (x)
answers
x^2 + 3x + 1
x^2 + 3x-1
4x^2 - 1
2x + 3

Answer 1

just add the 2 functions
3x - 2 + x^2 + 1 =

Answer 2

i dont know

Answer 3

what do you mean by add the second functions? Like add the 3x-2 + x^2 + 1? or what?
@cwrw238

Answer 4

not add the second functions, add the two functions
i think you added them wrong, look at the constant terms

Answer 5

you can only add like terms ;- x^2 + 3x cannot be added but you can add the 2 constants

Answer 6

so the 2 and the 1
?

Answer 7

the -2 and the 1
- don't forget the sign!

Answer 8

B? because the answer comes to -1..

Answer 9

(f + g) (x) = f(x) + g(x)
= (3x -2) + (x^2 + 1)
like @cwrw238 said you can only add like terms

Answer 10

yes

Answer 11

ok thanks!!
