Given u = 〈3,1〉 and v = 〈−4,2〉, write each vector in component form, graph it, and explain the geometric effect.
a. 3u
b. 1/2v
c. −2u
d. −v
e. u + v
f. 2u + 3v
g. 4u − 3v
h.1/2u −1/3v

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

hd extra 3-7 x d en is the answer

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
