The expression for the function f(x) + g(x) is given as 7x + 2 with a domain of f(x) + g(x) from (-∞, ∞)

What is a function?

A function is an expression that shows the relationship between two or more variables and numbers.

Given that  f(x) = 4x – 5 and g(x) = 3x + 7. Hence:

f(x) + g(x) = (4x - 5) + (3x + 7) = 7x + 2

The domain of f(x) + g(x) is (-∞, ∞)
