Question

Given the polynomial function below, find F(-1).

F(x) = -x3 - x2 + 1

Answer 1

Answer : The value of polynomial function when F(-1) is, 1

Step-by-step explanation :

As we are given the polynomial function:

$F(x)=-x^3-x^2+1$

Now we have to calculate the value of polynomial function when F(-1).

When F(-1) that means, the value of 'x' is (-1).

Now put the value of 'x' in above polynomial function, we get:

$F(x)=-x^3-x^2+1$

x = (-1)

$F(-1)=-(-1)^3-(-1)^2+1$

$F(-1)=-(-1)-(1)+1$

$F(-1)=(1)-(1)+1$

$F(-1)=1$

Thus, the value of polynomial function when F(-1) is, 1
