Question

Given the polynomial function below, find F(-1). F(x) = -x ^3 - x ^2 + 1

Answer 1

Answer:

$f(-1) = 1$

Step-by-step explanation:

Given

f(x) = $-x^{3}-x^{2} +1$

Finding f(-1) means, we have to put -1 in the places of x in the function,

So, putting x=-1 in the function

$f(-1) = (-1)^{3} - (1)^{2} +1$

As the power 3 is odd, the minus will remain the same, while in the 2nd term minus will be eliminated due to even power. So,

=> $-1-1+1$

=> 1

Hence,

$f(-1) = 1$
