Multiple choice question, person that show's the most work gets brainliest, question is down below.

(- 1 + √3)/2

rationalise the denominator by multiplying the numerator/denominator by the conjugate of the denominator.

the conjugate of 1 + √3 is 1 - √3

(1 - √3)/(1 + √3)(1 - √3) = (1 - √3)/( 1² - (√3)²) = (1 - √3)/(1 - 3) = (1 - √3)/(- 2)

multiply numerator/denominator by (- 1)

=(-1 +√3)/2

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
