Final answer:
To determine f(1), we can use the function f(x) defined by the ordered pairs {(-2,-5),(-1,-2),(0,1),(1,4),(2,7)}. When x equals 1, the value of y equals 4, so f(1) equals 4.
Step-by-step explanation:
To determine f(1), we need to find the value of y when x equals 1 using the function f(x) defined by the ordered pairs {(-2,-5),(-1,-2),(0,1),(1,4),(2,7)}. We can see that when x equals 1, y equals 4, so f(1) equals 4.
