Given the graph below, which of the following statements is true?

The graph represents a one-to-one function because every x-value is paired with only one y-value.

The graph represents a one-to-one function because it is defined for all x-values.

The graph does not represent a one-to-one function because it does not pass through the origin.

The graph does not represent a one-to-one function because the y-values between 0 and 2 are paired with multiple x-values.

Which of the following graphs represents a one-to-one function?

On a coordinate plane, a function has two curves connected to a straight line. The first curve has a maximum of (negative 6, 4) and a minimum of (negative 4.5, negative 1). The second curve has a maximum of (negative 3.5, 2) and a minimum of (negative 2.5, 0.5). The straight line has a positive slope and starts at (negative 2, 1) and goes through (1, 2).

On a coordinate plane, a circle intersects the x=axis at (negative 2, 0) and (2, 0) and intercepts the y-axis at (0, 4) and (0, negative 4).

On a coordinate plane, a v-shaped graph is facing up. The vertex is at (0,0) and the function goes through (negative 4, 4) and (4, 4).

A coordinate plane has 7 points. The points are (negative 4, 1), (negative 3, 4), (negative 1, 3), (1, negative 3), (3, negative 4), (4, negative 2), (5, 3).
