Help a friend out plz! Graph on the domain {-pi, 0], where a = 3 and b =2 and include the orientation. x(t) = acos((a+b) t) & y(t) = acos((a-b)t) Use the parametric equations for integers a and b.

step-by-step explanation:

did you get the answer yet?

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
