Looking at the graph, we can see that for x < 1 (number 1 not included), the graph has a quadratic behavior, and for x >= 1 the graph has a linear behavior.
In the quadratic part, the y-intercept is 3, so the value of c in the standard form (y = ax² + bx + c) is zero.
Knowing that the value of c is 3 for the quadratic part and that the quadratic part occurs for x < 1, the only corresponding option is the first option.
