A family of cubic functions have zeros of -2 and $4\pm \sqrt{7}$ .

4) Write the equation ofthe family of cubic Functions in factored form. The equation may contain a ‘non-factorable quadratic but should contain no radicals. Show your work,

b) Write the equation for the member which goes through the point (2, -72). Show vour work,

c) Describe the end behaviour for the member in b).

Step 1

Family of cubic functions that have the roots a,b and c is

Given roots are:

(a)

Step 2

(b) Substitute

For cubic equation which goes through point (2, -72) substitute

we get,

The graph

the three roots
