For the following exercises, use a calculator to find the answer. 54. The path of an object rejected at a 45 degree anglewith initial velocity of 80 feet per second is givenby the function h ( x ) = − 32 ( 80 ) 2 x 2 + x where x is thehorizontal distance traveled and h ( x ) is the heightin feet. Use the [TRACE] feature of your calculatorto determine the height of the object when it hastraveled 100 feet away horizontally.

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
