Q. Find the yy-intercept of the parabola y=x27y = x^2 - 7. \newlineSimplify your answer and write it as a proper fraction, improper fraction, or integer.\newline__\_\_
  1. Find y-intercept: To find the y-intercept of the parabola, we need to determine the value of yy when x=0x = 0.
  2. Substitute x=0x=0: Substitute x=0x = 0 into the equation y=x27y = x^2 − 7.\newliney=(0)27y = (0)^2 − 7\newliney=07y = 0 − 7\newliney=7y = -7
  3. Determine yy value: The yy-intercept of the parabola is the point where the parabola crosses the yy-axis, which occurs at (0,y)(0, y). Since we found y=7y = -7 when x=0x = 0, the yy-intercept is at (0,7)(0, -7).
