Factored Form and Graph

What is the equation of the graph?

• y= x(x-2)(x-4)

• y= x(x-2)(x-4)²

• y= x(x-2)²(x-4)

• y= x²(x-2)(x-4)

Which equation matches the given graph? Use desmos.com to play around with a-values until your y-intercept matches.

• y = -(x+3)(x+1)(x-2)
  

• y = -.5(x+3)(x+1)(x-2)
  

• y = .5(x+3)(x+1)(x-2)

• y = -2(x+3)(x+1)(x-2)

Create a STANDARD FORM rule that matches the graph

• y = (x + 3)(x - 2)

• y = x² - x - 6

• y = x² + 3x - 2

• y = x² + x - 6

What is the error?

• The student found the wrong x intercepts

• The student forgot to flip the signs of the intercepts in the equation

• the student forgot to square the factor of the double root factor

• The student wrong a function for a cubic function instead of a quadratic function
