Why might the rate of change pattern not be useful for all quadratic equations?

• It only applies to linear functions

• It can be too complex to calculate

• Some quadratics do not have a clear vertex

• All options are correct

What alternative method is suggested for graphing when the rate of change pattern is not suitable?

• Using a graphing calculator

• Plugging values into the equation

• Estimating the graph shape

• Ignoring the vertex
