Q. Find the y-intercept of the parabola y=x2−5x+7. Simplify your answer and write it as a proper fraction, improper fraction, or integer._____
Find y-intercept: To find the y-intercept of the parabola, we need to evaluate the function y=x2−5x+7 at x=0, because the y-intercept occurs where the graph of the function crosses the y-axis, and the x-coordinate is always 0 at the y-axis.Calculation: y(0)=(0)2−5(0)+7=0−0+7=7
