8-78.

For each of the following sets of numbers, what is the equation of a function that has these numbers as roots? Homework Help ✎

–3 +

*i*and –3 –*i*5 +

and 5 – –2,

, and – 4, –3 +

*i*, and –3 –*i*

Refer to problems 8-65 and 8-67.

*y* = *x*^{2} − 10*x* + 22

You will need to write a product of three linear factors for this one.

*y* = *x*^{3} + 2*x*^{2} − 7*x* − 14

You can use your answer from part (a) to get started.
