Q. Find the yy-intercept of the parabola y=x2−7x+9y = x^2 - 7x + 9. Simplify your answer and write it as a proper fraction, improper fraction, or integer.\newline_____
  1. Evaluate Function at x=0x = 0: To find the y-intercept of the parabola, we need to evaluate the function y=x2−7x+9y = x^2 − 7x + 9 at x=0x = 0, because the y-intercept occurs where the graph of the function crosses the y-axis, and the x-coordinate is always 00 at the y-axis.\newlineCalculation: y(0)=(0)2−7(0)+9=0−0+9=9y(0) = (0)^2 − 7(0) + 9 = 0 − 0 + 9 = 9
