The graph of which function has a y - intercept of 3?
- On a coordinate plane, a parabola opens up. It goes through (-3, 3), has a vertex at (-1.5, 0.75), and goes through (0, 3).
- On a coordinate plane, a parabola opens up. It goes through (1, 4), has a vertex at (3, 0), and goes through (5, 4).
- On a coordinate plane, a parabola opens up. It goes through (-5, 4), has a vertex at (-2, 4), and goes through (-1, 4).
- On a coordinate plane, a parabola opens up. It goes through (-4, 5), has a vertex at (-1, -4), and goes through (2, 5).

Answer:

  (a)  ... goes through (0, 3)

Step-by-step explanation:

You want to identify the graph that shows a function with a y-intercept of 3.

Y-intercept

The y-axis corresponds to the vertical line x=0, so the point that represents a y-intercept of 3 will have coordinates (x, y) = (0, 3).

The first answer choice (A) describes a graph that includes the point (0, 3).

Additional comment

The third answer choice says it is a parabola, but it is actually a horizontal line: y = 4.
