f(x)=-6x-1 and g(x)=4x^2. Select the solution for (f+g)(x). a) -6x-1+4x^2 b) -24x^3 -4x^2 c) -24x^2 -1 d) -6x-1-24x^2

Question

multiple choice:  a) -6x -1 +4x^2  b) -24x^3 -4x^2  c) -24x^2 -1   d) -6x -1 -24x^2

 

Answer 1

first thing to know: (f+g)(x)=f(x)+ g(x)

 

f(x)=-6x-1 and g(x)=4x^2

 

so (f+g)(x)=(-6x-1)+(4x²)
