Describe the following relation using the roster method.

The graph of relation E

E = {(x, y) : x 0, y 0}

A. E = {(x, y) : x 0, y 0}   

B. E = {(x, y) : x 0, y 0}

C. E = {(x, y) : x 0, y 0}

D. E = {(x, y) : x > 0, y < 0}

Solution

the shaded region in the graph describes nonnegative x values and nonpositive y values

C. E = {(x, y) : x 0, y 0}
