Determine whether the vectors u and v are parallel, orthogonal, or neither. u = <10, 0> , v = <0, -9>
A. Parallel
B. Orthogonal
C. Neither

i think it is 18

step-by-step explanation:

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.

i think this is a open ended question but i agree with other guy who said you should ask it at english section
