What is the domain of the relation? Oa. {-1,0, 1, 3)
Oc. { -2,-1, 0, 1, 2, 3}
Ob.{-2, 0, 1,3}
Od. {0, 1, 2, 3}

(03.01) The domain of a relation is the output (y) values of the relation the input (x) values of the relation a set of points that pair input values with output values x and y values written in the form (x, y)

which expression represents the approximate length of bc?

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
