Answer:
We can determine if the graph shows a function by using the vertical line test.
If we draw a vertical line and there are 2 or more points on that line than the graph is not a function. This is because each x value has one corresponding y value. If an x value has more corresponds to more than one y value than the relation is not a function.
If we were to draw a vertical line at x = 5, 2 points would be one that line meaning that the x value 5 corresponds to more than 1 y value, therefore the graph does not show a function.
Answer: The answer is not 1 it's 2
Step-by-step explanation:
Multiply 4*1 to get 4
Multiply 1*2 to get 2
Your answer should be 4/2 which equals 2
Answer:
C = 2πr
Step-by-step explanation:
The circumference of a circle is calculated by the formula here,
C is the circumference of the circle.
r is the radius of the circle.
π is 22/7 or 3.14.
In the given options π is not missing.
Therefore the formula that relates circumference and radius is C = 2πr.
4n-2n=6
2n=6
n=6/2
n=3
Your answer is C. 3
N-1(-1/2) is the formula because the sequence is taking half of the previous number and changing its sign
