ASAP No nonsense answers, and attach solutions please!

Step-by-step explanation:

When x is -2, F(x) is undefined.

When x is -1, F(x) is -3.

If we see the third option,

When x is -2, we get the square root of -1, which is undefined.

When x is -1, we get the square root of 0, which is just 0, 0-3 is -3.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

two? xd
