Q. Find the y-intercept of the parabola y=x2−7. 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 determine the value of y when x=0.
Substitute x=0: Substitute x=0 into the equation y=x2−7.y=(0)2−7y=0−7y=−7
Determine y value: The y-intercept of the parabola is the point where the parabola crosses the y-axis, which occurs at (0,y). Since we found y=−7 when x=0, the y-intercept is at (0,−7).
