Find the equation in factored form. y=a(x - r)(x - 5)(x - t) 1. I'm a cubic with a double root at -4 and a root at 2. The point (0, 96) is on me.

How to do this , and can some one explain

Use circumcenter theorem to solve for the given values

The population of a small rural town in the year 2006 was 2,459. the population can be modeled by the function below, where f(x residents and t is the number of years elapsed since 2006. f(t) = 2,459(0.92)
