Question

A one-to-one function f is given in the form of a set of ordered pairs below: {(-5, -10), (0, -2), (2, 2), (8, 6), (10, 4)}. What is the value of f(10)?

a) 4
b) 6
c) 2
d) -2

Answer 1

By examining the set of ordered pairs, we determine that the value of function f at x=10 is 4, represented by the ordered pair (10, 4).

Step-by-step explanation:

The student is asking for the value of the function f at x=10. This type of function is represented as a set of ordered pairs where each first element corresponds to one and only one second element, defining a one-to-one function.

The given set of ordered pairs for the function f is {(-5, -10), (0, -2), (2, 2), (8, 6), (10, 4)}. To find f(10), we look for the ordered pair where the first element is 10. In this case, we find the ordered pair (10, 4), which means that f(10) = 4.
