When Evil Kenevil was a kid, he decided to attempt to jump a distance of 30 yards using ramps that extended 9 yards high for take off and landing with his motorcycle. As the figure below illustrates, at zero yards from the take off ramp, he was 9 yards high. At 8 yards from the ramp, he was 17 yards high, and at 18 yards from the ramp, he was 18 yards high. Since there are no rockets or wings affecting Evil’s flight, he should closely follow a parabolic path that can be modeled by a quadratic equation: y=ax^2+bx+c, where y is the height of Evil’s bike, and x is the horizontal distance he has traveled. Using the three data points (x, y) that we know Evil passed through and the general quadratic equation, create three corresponding equations: Equation 1:

Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity
