Answer 1

Ответ:

2x²+4x+3

При х=-2

2(-2)²+4*(-2)+3=3

Ответ: у=3

Answer 2

Calculating the Value of a Function

To find the value of the function y = 2x² + 4x + 3 when x = -2, we can simply substitute x = -2 into the function and perform the necessary calculations.

Substitute x = -2 into the function: y = 2(-2)² + 4(-2) + 3

Now, let's calculate the value of y.

Perform the calculations: y = 2(4) - 8 + 3 y = 8 - 8 + 3 y = 3

Therefore, when x = -2, the value of the function y = 2x² + 4x + 3 is 3.
