Q. Find the y-intercept of the parabola y=x2+x−435. Simplify your answer and write it as a proper fraction, improper fraction, or integer._____
Evaluate y-intercept: To find the y-intercept of the parabola, we need to evaluate the equation y=x2+x−435 at x=0, because the y-intercept occurs where the graph of the parabola crosses the y-axis, and the x-coordinate is always 0 at the y-axis.Calculation: y=(0)2+(0)−435=−435
