Mathematics

(A) degree of 2; 1 ± i√7

Step-by-step explanation:

Degree of the polynomial designates the number of roots.

x² - 2x + 8

a=1 b=-2 c=8

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$=\dfrac{-(-2)\pm\sqrt{(-2)^2-4(1)(8)}}{2(1)}$

$=\dfrac{2\pm\sqrt{4-32}}{2}$

$=\dfrac{2\pm\sqrt{-28}}{2}$

$=\dfrac{2\pm2i\sqrt{7}}{2}$

$=\dfrac{2(1\pm\\i\sqrt7)}{2}$

= 1 ± i√7

Mathematics

y = cos x + 2

Step-by-step explanation:

The graph of y = cos x begins at y=1 when x=0, that is, at (0, 1). If we translate the entire graph of y = cos x upward by 2 units, we get the graph shown. The correct answer is b: y = cos x + 2.
