Question

F (x) = 3 x -1 and g(x) = x+ 2,find (f+ g) (x)

Answer 1

(f+g)(x) = 4x + 1

Explanation:

Rewrite these two functions vertically for ease in combining like terms:

f (x) = 3 x -1

+g(x) = x+ 2

Combining like terms, we obtain:

f (x) = 3 x -1

+g(x) = x+ 2

-------- ---------

(f+g)(x) = 4x + 1
