Use the graph to determine the domain and range of the relation, and whether the relation is a function.

a. domain: {x| -8, 8}; range: all real numbers; no, it is not a function.

b. domain: {x| -8 x 8}; range: all real numbers; yes, it is a function.

c. domain: {x| -8 x 8}; range: all real numbers; no, it is not a function.

d. domain: {x| -8 x 8}; range: {y| -12 x 12}; yes, it is a function
