Answer:

$f(x) = 2{x}^{2} - x + 5 \\ f( - 2) = 2 {( - 2)}^{2} - ( - 2) + 5 \\ f( - 2) = 2(4) + 2 + 5 \\ f( - 2) = 8 + 2 + 5 \\ \boxed{f( - 2) = 15}$

f(-2) = 15 is the right answer.

Answer:

see below

Step-by-step explanation:

side opposite 90 angle = x $\sqrt{2}$

sides opposite 45 angle = x

the multiplication and division by $\sqrt{2}$ should be self explanatory

1. x = 5, y = 5

2. v = 10, u = 10

3. x = $\sqrt{10}$ , y = $\sqrt{5}$

4. m = 5, n = $\frac{5\sqrt{2} }{2}$

5. a = $\frac{3\sqrt{2} }{2}$ , b = $\frac{3\sqrt{2} }{2}$

6. a = $\frac{3\sqrt{2} }{2}$ , b = $\frac{3\sqrt{2} }{2}$
