How to do rate of change

1.2 Average Rate of Change of a Function. To get the average rate of change of f f from x = a x = a to x = b x = b, we compute the following ratio: Avg. Rate of Change = f (b)− f (a) b− a or Δf Δx Avg. Rate of Change = f ( b) − f ( a) b − a or Δ f Δ x. Let’s try an example.

The rate of a chemical reaction is determined—and altered—by many factors, including the nature (of reactivity) of reactants, surface area, temperature, concentration, and catalysts. For each unique chemical reaction, rate laws can be written at a rate law equation to show how the concentrations of reactants affect the rate of the reaction. This method is more difficult to use if "a" is not an integer. Form: y = ax2 + bx + c or Vertex Form: y = a ( x - h) 2 + k. Steps for Using the Rate of Change Pattern and Vertex to Graph: 1.
