Q. Find the y-intercept of the parabola y=x2−219. Simplify your answer and write it as a proper fraction, improper fraction, or integer._____
Evaluate at x=0: To find the y-intercept of the parabola, we need to evaluate the equation y=x2−219 at x=0, because the y-intercept occurs where the graph of the equation crosses the y-axis, and the x-coordinate is always 0 at the y-axis.
Substitute x=0: Substitute x=0 into the equation y=x2−219 to find the y-intercept.y=(0)2−219y=0−219y=−219
Find y-intercept: The y-intercept of the parabola y=x2−219 is the point (0,−219).
