Let f(x)equals
7xplus4
and g(x)equals
4xminus5.
Find (fplus
g)(x),
(fminus
g)(x),
(fg)(x), and left parenthesis StartFraction f Over g EndFraction right parenthesis
(x).
Give the domain of each.

Step-by-step explanation:

We have , f(x) = 7x + 4 & g(x) = 4x-5.

A: ( f + g )( x )

We know that sum of two functions is as simple addition so,

B: ( f - g ) ( x )

We know that difference of two functions is as simple subtraction so,

C:( fg ) (x)

We know that multiply of two functions is as simple multiplication so,

D: (f/g)(x)

We know that Division of two functions is as simple division so,

Since, both f(x) and g(x) are real valued functions , ∴ Domain of both are real numbers.
