Factor
(x+7)(x-2)
Proof
7-2=5
7*-2=-14
Zeros
x+7=0
x=-7
x-2=0
x=2
Final answer: C
A relation is a function if it passes the vertical line test. That graph in a coordinate plane is just a sin wave that is spread out. If you run a perfectly vertical line through the graph at every place on the graph, the line you draw will only go through the graph at one place every time. That makes it a function. It's not a one-to-one function cuz it fails the horizontal line test, but it is a function!
Answer:

Step-by-step explanation:
We have:

For sine use:

Substitute:

θ in IV quadrant, therefore sine is negative.

For tangent use:

Substitute:

20/30 = 2/3
18/27 = 2/3
