Rudik [331]2 years ago

Answer: Option a.

Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

We have the function f(x) = 2x + cosx

Note that f(x) is the sum of two continuous functions h(x) = 2x and g(x) = cosx

The domain and range of h(x) are all real numbers

The domain of g(x) is all real numbers. The range of g(x) is [-1, 1]

Then the domain of f(x) = h(x) + g(x) will be <u>the intersection</u> of the domains of the function h(x) = 2x and the function g(x) = cosx.

Therefore <u>the domain of f(x) are all real numbers</u>.  x ∈ (-∞, ∞)

The range of f(x) will be equal to<u> the union</u> of the range of g(x) and h(x)

Therefore <u>the range will be all real numbers f(x) </u>∈ (-∞, ∞)
