Question

The function f(x) is given by the set of ordered pairs.

{(1,0), (–10,2), (0,6), (3,17), (–2,–1)}

Which equation is true?

f of negative 10 = 1
f of 2 = negative 10
f of 0 = 6
f of 1 = negative 10

Answer 1

Look for the ordered pair whose first coordinate matches the input.

(0, 6) is in the set, so f(0) = 6.
