The domain (input values) of the cosine function is all negative and positive angle measures.
Let the function be f(x) = cos(x)
The domain of cos(x) is -∞ < x < ∞
The range is -1 ≤ f(x) ≤ 1
Hence, domain of cos(x) is all (+) and (-) angle measures.
Same goes with sine function as well
For function f(x) = sin(x)
The domain is -∞ < x < ∞ and range -1 ≤ f(x) ≤ 1
However for f(x) = tan(x) the same is not applicable.
Answer: y = 2x + 9
<u>Step-by-step explanation:</u>
slope(m) = 
= 
= 
= -2
Point-Slope formula: y - y₁ = m(x - x₁)
y - 5 = -2(x - 2)
y - 5 = -2x + 4
y = 2x + 9
Luke’s brother will now make $15.90 per hour.
It is equal. The same either way. :)
