For the equation y = -x^2 + 2x + 3, what is the y-intercept?

Explanation:
When you want the y-intercept, look at the value of y when x is 0, since the y-axis is where x equals 0. For y = -x^2 + 2x + 3, the constant term is 3, and evaluating at x = 0 gives y = -(0)^2 + 2(0) + 3 = 3. So the graph crosses the y-axis at (0, 3), meaning the y-intercept is 3.
