Which of the following is the value of the expression 2x^2+1 when x = - 2?

2 (-2) ^2+1

2 (4) + 1

8+1

9

The value of this expression is 9 when x=-2

Answer: 9

Step-by-step explanation:

1.) you first want to plug in your x = - 2

2.) 2*-2^2=1

3.) Solve in order.

4.) 2*-2 = - 4

5.) - 4 * - 2 (your power) = 8, it is a negative two because x = - 2 and where it lands in the order of operations that is how you solve.

6.) 8 + 1 = 9

7.) = 9.
