### Kim Modelling Functions

1. 1. Modelling<br />Kim Dart<br />
2. 2. Modelling <br />When you’re given an equation that is missing a certain variable or constant and certain points (x,y) on the graph, and are asked to find that variable by inserting the given points into the equation.<br />
3. 3. Modellingona Calculator<br />
4. 4. Modelling Involving Exponential Functions<br />The rule for the function of a graph is of the form y = aex + b. The graph passes through the points (0,6) and (3,22). Find the values of a and b.– Do question on the board.<br />(Solution page 177 of text book)<br />
5. 5. Questions<br />Complete;<br />Exercise 5.E. Q.1,2<br />
6. 6. Modelling Involving Logarithmic Functions<br />The rule for the function of a graph is of the form y = aloge(x+b). The graph passes through the points (5,0) and (8,1). Find the values of a and b. – Do question on the board.<br />(Solution page 177 of text book)<br />
7. 7. Questions <br />Complete;<br />Exercise 5.E; Q5,8<br />
8. 8. Modelling Involving Circular Functions<br />A function with rule y=Asin(nt)+b had range [2,8] and period 2π/3. Find the values of A, n and b. Do question on the board.<br />
9. 9. Questions <br />Complete;<br />Exercise 6.J; Q.5,7.<br />
