Steve · Answer 1

The answer is B. The y-intercept is the number on the y axis when x=0. you can see that when x=0, y=3, therefore B is the answer

Pablo Hodge · Answer 2

Y-intercept is the value of f (t) when t = 0. From the table, when t = 0, f (t) i. e. height = 3.

Therefore, the second option is the correct answer.
