Answer:
Yes
Step-by-step explanation:
Given
[tex]A = \{a, b, c\}[/tex]
[tex]B = \{4, 5, 6\}[/tex]
[tex]f = \{(a, 6), (b, 4), (c, 6)\}[/tex]
Required
Is f a function of A->B
f can be rewritten as
x --- y
a -- 6
b -- 4
c -- 6
The x column is regarded as the input while the y is the output
Notice that for every input, there is a corresponding output and no input points to multiple outputs.
i.e No value of x has more than 1 value of y
Because of this singular reason; f is a function of A->B
