Q. Find the y-intercept of the parabola y=x2+2. 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+2.y=(0)2+2y=0+2y=2
Identify y-intercept point: The y-intercept of the parabola is the point where the graph crosses the y-axis, which occurs at (0,y). Since we found y=2 when x=0, the y-intercept is at (0,2).
