Question

If f(x) is a function and f(1) = 5, then which of the following could not be true?


f(1) = 1
f(2) = 1
f(5) = 5

Answer 1

f(1) = 1
f(2) = 1
f(5) = 5

Answer 2

okay

Answer 3

f(1) = 1 can't be true.
For all functions, any one input value will only have one output value, but multiple inputs can have the same output.

Answer 4

If f(x) is a function it can have only one value per x value, so f(1) = 1 cannot be true
