Answer:

The answer should be c

Step-by-step explanation:

whenever you are trying to determine whether a graph determines a function or not, just draw a vertically straight line through the graph's line. If you draw that line and it goes through the graph's line more than once, then the graph does not represent a function.

The answer is C however I always felt the “vertical line test” was for people who can’t do math and need images. A function is any equation that does not have same out come with different numbers I.E x^2 is not a function.

Answer:

$\frac{2}{5}\vec{a}+\vec{b}$

Step-by-step explanation:

$\vec{DE}=\vec{DB}+\vec{BE}$

$=\frac{3}{5}\vec{OB}+\frac{1}{5}\vec{BC}$ $\left\{OD:DB=2:3,BE:EC=1:4\right\}$

$=\frac{3}{5}\left(\vec{OA}+\vec{AB}\right)+\frac{1}{5}\left(\vec{BA}+\vec{AO}+\vec{DC}\right)$

$=\frac{3}{5}\left(\vec{a}+\vec{b}\right)+\frac{1}{5}\left(-\vec{b}-\vec{a}+\vec{3b}\right)$

$=\frac{2}{5}\vec{a}+\frac{2}{5}\vec{b}+\frac{3}{5}\vec{b}$

$=\frac{2}{5}\vec{a}+\vec{b}$
