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:
C
Step-by-step explanation:
The answer is 6 degree.
Step by step process
The formula for calculating the measure of each exterior angle of a polygon is (360/n).
The number of sides of 56-gon(n) = 56.
So, each exterior angle
= (360/56)
= 6.43 or
6(approximately)
Since x=2, you plug it into your equation by replacing all the x with 2. You would then solve it by following the PEMDAS rule.
y= 4(2) + 2(2)^2 - (2)^3
y= 4(2) +2(4) - 8
y= 8 + 8 - 8
y= 16 - 8
y= 8
The answer is the second one x=-1/2
