Full solution stays hidden until you ask for it.
1. Substitute x=0 into the polynomial.
2. Simplify the output.
3. Write the y-intercept as (0,f(0)).
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using roots as y-intercepts unless x=0 is a root.
