Answer:
Th red curve is the graph for the given equation.
Step-by-step explanation:
We are given the function:
We have to graph the given function.
Properties of given function are:
- The given function is a linear function of the form
- Here, a = 5 and b = -2.
- The function is a straight line.
- When x = 0, f(x) = -2
- When f(x) = 0, x =
- The domain of the given function is all real numbers.
- The range of the given function is all real numbers.
The attached image shows the graph for the given function.

Answer:
For a point defined bt a radius R, and an angle θ measured from the positive x-axis (like the one in the image)
The transformation to rectangular coordinates is written as:
x = R*cos(θ)
y = R*sin(θ)
Here we are in the unit circle, so we have a radius equal to 1, so R = 1.
Then the exact coordinates of the point are:
(cos(θ), sin(θ))
2) We want to mark a point Q in the unit circle sch that the tangent has a value of 0.
Remember that:
tan(x) = sin(x)/cos(x)
So if sin(x) = 0, then:
tan(x) = sin(x)/cos(x) = 0/cos(x) = 0
So tan(x) is 0 in the points such that the sine function is zero.
These values are:
sin(0°) = 0
sin(180°) = 0
Then the two possible points where the tangent is zero are the ones drawn in the image below.
