  5. More examples of quadratic functions in the real world Next Prev

  6. Quadratic functions Standard form: x2 y x2 c or a + = f(x) + c a = a c Where: = coefficient = constant Next Prev

  7. Quadratic functions Graphing a quadratic function: Option 1 : Make a table of values (T-table) Place the ordered pairs on the coordinate plane Join the points with a smooth curve The graph is also called a Parabola Option 2 : Transform the equation into y=ax2 + c Use the calculator Next Prev

  8. Quadratic functions Example: Graph: y = x2 Y 4 4 y=(-2)2 => y= 4 4 -2 1 1 -1 y=(-1)2 => y= 1 1 -X X 0 0 y=(0)2 => y= 0 0 1 y=(1)2 => y= 1 1 2 y=(2)2 => y= 4 4 -Y Next Prev
