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

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 .

2(-2)^2+1

2(4)+1

8+1

9

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