Answer:
ƒ(x) + g(x) = 7x - 2
(-∞, ∞) or -∞ < x < ∞
Step-by-step explanation:
ƒ(x) = 4x - 5
g(x) = 3x + 7
ƒ(x) + g(x) = 4x - 5 + 3x + 7 = 7x - 2
The domain is the set of all possible x-values that will make a function work.
x can take any value from -∞ to ∞.
The domain is (-∞, ∞) or -∞ < x < ∞.
The diagram shows the graphs of ƒ(x) (red), g(x) (blue), and the solid green line is the graph of ƒ(x) + g(x). The line extends indefinitely in both directions,
