Given h(x)=(3x-4), f(x)=(-7x+2), and g(x)=(9x+1), which of the following is equivalent to 2x+3?

f+g is right answer.

Step-by-step explanation:

given

,

2x+3 is given and we have to find the combinations of h,f and g.

By trial and error we check h+f

= -4x-2

h-f = 10x-6

So these two are not correct

Try with h+g = 12x-3 and h-g = -6x-5

Hence these are also not right

Try with f+g

(f+g)(x) = f(x)+g(x) = -7x+2+9x+1 =2x+3

Hence f+g is right.
