10.1 Exercise 10

For each set of ordered pairs, determine if it represents a function and, if so, if the function is one-to-one.

ⓐ $\left\{\left(−3 , 27\right) , \left(−2 , 8\right) , \left(−1 , 1\right) , \left(0 , 0\right) , \left(1 , 1\right) , \left(2 , 8\right) , \left(3 , 27\right)\right\}$ and ⓑ $\left\{\left(0 , 0\right) , \left(1 , 1\right) , \left(4 , 2\right) , \left(9 , 3\right) , \left(16 , 4\right)\right\} .$
