Q. Find the y-intercept of the parabola y=x2+5x+10. 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+5x+10 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+5x+10 to find the y-intercept.y=(0)2+5(0)+10y=0+0+10y=10
Find y-intercept: The y-intercept of the parabola y=x2+5x+10 is the point (0,10).
