find a f2 and b f1 f1347 0622SolutionGiven that f 13 47 0

find (a) f(2) and (b) f(-1)

f={(-1,3),(4,7), (0,6),(2,2)}

Solution

Given that f = { (-1,3) , (4,7), (0,6), (2,2)}

ordered pair (x , y) ==> y = f(x)

a) f(2)

we have the ordered pair (2 , 2)

==> f(2) = 2

b) f(-1)

we have ordered pair (-1 , 3)

==> f(-1) = 3
