Determine f(9). Refer to the function f={(2,3),(9,7),(3,4),(-1,6)}

jimthompson5910 (jim_thompson5910):

f(9) means "the y coordinate when x = 9"

jimthompson5910 (jim_thompson5910):

so which ordered pair has an x coordinate of 9?

OpenStudy (anonymous):

7. I missed that. I didn't understand to instructions well.

jimthompson5910 (jim_thompson5910):

therefore, f(9) = 7

Thanks.
