You can put this solution on YOUR website! A function f is defined by {(0, 5), (1, 2), (2, 4), (5, 6), (7, 9)}.What is the value of f(5)?
.
Each pair is defined as:
(x, f(x))
.
Therefore, to find the value of f(5)
we look for the first number in the pair to be a 5:
(5, 6)
Therefore, the "value of f(5)" is 6
