Q. Find the yy-intercept of the parabola y=x2+4xy = x^2 + 4x. \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 evaluate the equation at x=0x = 0, because the y-intercept is the point where the graph of the equation crosses the y-axis, and at this point, the value of xx is always 00.
    Calculation: y=(0)2+4(0)=0+0=0y = (0)^2 + 4(0) = 0 + 0 = 0
