Cheek solutions to Test 3 on Moodle. The first 4 graphs are obtained by the product of two functions. One of the fetors and if reflection across. the x-axis is also graphed (to enhance how the -amplitude of the sinusoidal rune is changing.) Match cadi graph with one of the possible formulas given. Then, find k for (c) and (f).

Solution

Here based on the functions nature, their graphs are matched as follows :

Function   Graph

a)              First left at top

b)              Top right   

c)              Bottom left

d)              Bottom rigthmost

e)              Graph that is in second row and second colum or in right side of middle row

f)               Graph that is in the second row first column in left side.

And these graph matches for value k=3 of the given function in option (e) and (f).
