Which relation is a function?
A. (3, -2), (4, 6), (-2, 6), (3, 1)
B. (-1, 4), (3, 2), (4, -2), (2, 4)
C. (2, -7), (-8, 2), (2, 4), (-1, 5)
D. (2, 2), (-3, -4), (-3, 1), (-2, 1)

B (-1,4), (3,2), (4,-2), (2,4)

Step-by-step explanation:

When this function is graphed, it passes the vertical line test. Another indicator that this is a function, is that not one x-coordinate is the same. So basically, the x-coordinates must always be different in order for a set of ordered pairs to be considered a function.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
