Sketch the vector field f(r) = -r / ||r||^3 in the xy-plane. select all that apply. a. the lengths of the vectors decrease as you move away from the origin. b. all the vectors point towards the origin. c. the length of each vector is 1. d. all the vectors point in the same direction. all the vectors point away from the origin.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
