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

A

Step-by-step explanation:

We can use vertical line test to determine if a relation is a function.

If a vertical line passes the graph at any point only once, then the relation is a function, if there is even 1 line that passes the graph at 2 points, then it is NOT a function.

The domain is the set of allowed x-values of the function. The range is the set of allowed y-values of the function.

Correct answer is A

the correct answer is c

false

inverse variation is not exponential
