About this simulation

A function is a rule, and its graph is the picture of that rule: every point on the curve is one input paired with the output the rule gives it. Typing the algebra and seeing the shape appear links the two directly, and changing one number at a time shows which part of the shape that number controls. Students can change x² coefficient and x coefficient and compare what happens. Use it for math inquiry with Middle School and High School on a projector or student device.

Standards: Common Core CCSS.MATH.CONTENT.8.F.A.3, CCSS.MATH.CONTENT.HSF.IF.C.7

What students can explore

  • Type x^2 and then x^2 - 3, and see that subtracting three slides the whole curve down
  • Plot two functions at once and find where they meet
  • Type 1/x and look at what happens as x approaches zero from each side
  • Use the trace point to read a value off the curve, then check it by hand
  • Find the x-values where a curve crosses zero, and connect them to solving the equation

Learning objectives

  1. 1Predict how changing x² coefficient will affect the value at the trace point, then test the prediction.
  2. 2Use evidence from the live calculation and visual to explain the result.
