Imagine that a graph of a function rule intersects the y-axis at some point. what do the coordinates of the intersection indicate? a. the function's input when the output is 1. c. the function's input when the output is 0. b. the function's output when the input is 1. d. the function's output when the input is 0.

Option D is correct.

Step-by-step explanation:

A function takes an input say 'x' and assign it exactly one output say 'y'.  An intersection with the y-axis indicates that x is 0  

Here, x is the input, which is zero, and y is output.

So, option D is the answer - The function's output when the input is 0.

Whenever a line crosses an axis, the other coordinate is always 0. We can conclude that intersection with the x-axis is a point (x,0) and intersection with the y-axis is a point (0,y).
