Question

Is the relation shown below a function? Use the graph below to justify your response (0, 0), (2, 0), (2, 2), and (3, 4)

Answer 1

No.

Explanation:

No because the x-intercept repeat. If the y-intercept repeat it's ok, it would be a function, however if the x-intercept repeat the graph is NOT a function.

Answer 2

Explanation:

By looking at the points (2, 0) and (2, 2),

The x-value of 2 gives the y-values 0 and 2.

Since this is a one-to-many relationship,

it is not a function.
