A. Yes, because every x-value corresponds with a single y-value.
O O O
B. Yes, because every x- and y-value is positive.
C. Yes, because the number of x-values is the same as the number of
y-values
D. No, because two points with the same y-value have different x-
values.

D-No, because two points with the same y-value have a different x-value.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

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.
