Question

The answers are 0, 1, 3, and 3.5. I think the answer is 3 but I'm not sure

Answer 1

The y-intercept of any function is the point where the line intersect with the y-axis, at this point the value of x is zero.

If you look at the graph, the line intersects the y-axis at point (0,3), so the y-coordinate of the y-intercept is 3
