Determine whether the relation defines to be a function of . If a function is defined, give its domain and range. If it does not define a function, find two ordered pairs that show a value of that is assigned more than one value of . See Example 2.$$\begin{array}{|r|r|}\hline x & {y} \\\hline 1.6 & {0} \\{-3} & {-1} \\{2.5} & {20} \\{-7} & {0.1} \\{1.6} & {19} \\\hline\end{array}$$

and this problem, we're given the table of values to represent a relation of. What we want to determine is whether this relation is a function while remember, in order for a relation to be a function that means each X value is assigned toe on Lee won. Why value? So let's look at our table. Well, if you know this near the top of the table, the X value of 1.6 is assigned to zero. But if you know this in the last row of the table, 1.6 for X is also assigned toe a y value of 19. Because this X value is assigned to more than one y value, this is not a function now. The second part of our directions say if it's not a function come up with to order cares where it's X value is assigned to more than one. Why value? Well, we've essentially just done that. We've already found that 1.6 was assigned to zero and that 1.6. What's a sign to a Y value of 19
