Explore the Equation grapher simulation (below) for several minutes:
  • The axes of the graph are indicated by black lines and labels x and y.
  • The black "tick" marks represent a magnitude of 1 from the origin (0,0).
  • The polynomial function f(x)=ax2+bx+c is represented by the red line.
  • Try clicking around
  • Try dragging objects
  • Try sliding sliders

When you have finished exploring try the multichoice question. Once you have completed the multichoice question try one of the main activities.

Even Functions

While you were exploring you may have noticed that the function curves when you give the coefficient a a value different from zero. Which values for the polynomial coefficients best describe a function f(x) that has outputs of
  • f(0) = 1
  • f(-1) = 0
  • f(1) = 0
