Question

what are the critical numbers for x^3 + 2x^2-x+1

Answer 1

critical numbers, are the numbers that will make the function equal to zero. try to factor the
'x^3 + 2x^2-x+1' what are the zeros of this?

In other words, critical numbers, in this case, are the zeros of this function.

Answer 2

My bad, it is not a function, but you get the point.

Answer 3

is the answer for the f"(x)=6x+4
and wen you set this equal to zero would the answer be -2/3

Answer 4

-2.54 , 0.273 and .273 are the numbers

Answer 5

so those are the critical numbers??

Answer 6

\[x^3 + 2x^2-x+1=0\]

solve for x.
