Solve f(-1)=-1^3-2(-1^2)+(-1)-9

$$f ( - 1 ) = - 1 ^ { 3 } - 2 ( - 1 ^ { 2 } ) + ( - 1 ) - 9$$

Evaluate

$$-9$$

Solution Steps

Calculate 1 to the power of 3 and get 1.

$$-1-2\left(-1^{2}\right)-1-9$$

Calculate 1 to the power of 2 and get 1.

$$-1-2\left(-1\right)-1-9$$

Multiply 2 and -1 to get -2.

$$-1-\left(-2\right)-1-9$$

The opposite of -2 is 2.

$$-1+2-1-9$$

Add -1 and 2 to get 1.

$$1-1-9$$

Subtract 1 from 1 to get 0.

$$-9$$

Factor

$$-9$$
