Best ResponseYou've already chosen the best response.4Since it is asking f+g, you need to add the two expressions together. After simplifying, substitute the x for 2 for your final answer.

Best ResponseYou've already chosen the best response.0its f(x)=2^2+3x and g(x)=x2 what is (f+g)(2) so what i got it would equal 22

Best ResponseYou've already chosen the best response.4f+g=2x^2+3x+(x2) Simplify, then substitute the x with 2.

Best ResponseYou've already chosen the best response.1the question is asking for (f+g)(2) so let's figure out the f(x) + g(x) portion first. so we have \[f(x)= 2x^2 +3x\] and \[g(x) = x2 \] so what is f(x)+g(x)

Best ResponseYou've already chosen the best response.1then after obtaining f(x)+g(x) we combine like terms finally evaluate f(x)+g(x) when x = 2

Best ResponseYou've already chosen the best response.1let's take it one step at a time by first understanding that (f+g)(2) means that we need to find f+g and then evaluating the result of f+g when x = 2

Best ResponseYou've already chosen the best response.1so we just have to add because f(x) + g(x) means the f function + g function so given \[f(x) = 2x^2+3x \] and \[.g(x) = x2 \] what is f(x) +g(x) the notation I'm using is the same as f+g

Best ResponseYou've already chosen the best response.1it should look like \[2x^2+3x+x2 \] now we combine like terms only for the x portion so what's 3x+x ?

Best ResponseYou've already chosen the best response.1\[2x^2+4x2\] ok so now we evaluate this function when x = 2. so place x =2 inside of the x of that function ex. \[2(2)^2+4(2)2\]

Best ResponseYou've already chosen the best response.1what's (2)^2 since we have second power it means to write 2 two times (2)^2 > (2)(2) what's (2)(2)?

Best ResponseYou've already chosen the best response.1(2)(2) notation is the same as 2 x 2 notation

Best ResponseYou've already chosen the best response.1\[2(2)^2+4(2)2 \] \[2(4)+4(2)2 \rightarrow 8+82 \rightarrow 162=14\]
