Determine the x values that cause the polynomial function to be positive:

f (x) = (x+2) (x+1) (x-5) Determine the x values that cause the polynomial function to be positive:

f (x) = (x+2) (x+1) (x-5)

So here is how you determine the values of x that cause the polynomial function to be positive.

Set each one greater than zero: x+2>0 x+1>0 x-5>0

Then, solve for x on all three:

x > - 2 x > - 1 x > 5

so in order for the polynomial to be positive the answer is x > 5.

Hope this is the answer that you are looking for.
