X 1,2,3,4

Question

y -8 -6-1-2
is this an function

Answer 1

Yes, this is a function. A function is a relationship between two sets of values, where each input (X value) corresponds to exactly one output (Y value). In this case, each X value (1, 2, 3, 4) is paired with exactly one Y value (-8, -6, -1, -2). Therefore, it satisfies the definition of a function.
