What are the roots of the function f(x)=x^2+x-6 a. x=3 and x= -2 b. x= -3 and x= -6 c. x=1 and x=-6

For this case we have the following quadratic function:

We must find its roots. We can factor, looking for two numbers that when added to +1 and multiplied by -6. These are:

+3 and -2

Then, the factored form is:

So, the roots are:

hope this !

the cost function, c(x), is the total cost of manufacturing x units of the product. how many units must the company produce and sell if they wish to make a b. if the company produces and sells 2000 units, would they obtain a profit or loss?
