1. The problem asks to find the y-intercept of a function or equation. 2. The y-intercept is the point where the graph crosses the y-axis. 3. At the y-intercept, the value of $x$ is always 0. 4. To find the y-intercept, substitute $x=0$ into the equation and solve for $y$. 5. For example, if the function is $y = 2x + 3$, substitute $x=0$: $$y = 2(0) + 3 = 3$$ 6. Therefore, the y-intercept is at the point $(0, 3)$. 7. This method applies to any function or equation to find the y-intercept.
