Project 9: Using Quadratic Equations to Model Situations and Solve Problems
A Linear Function and a Quadratic Function
Practice this chapterA Linear Function and a Quadratic Function Here are graphs of a linear function and a quadratic function.
The quadratic function is defined by the expression The function h , defined by h ( t ) = - 5 t 2 + 10 t + 7.5 , models the height of a diver above the water (in meters) t seconds after the diver leaves the board.
quadratic function — defined by the expression.
Be able to write an equation representing the line that passes through each pair of points. ( 3 , 3 ) and ( 5 , 5 ); solve this equation: x + 1 = ( x - 2 ) 2 - 3 . Show your reasoning.
