Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The function is increasing on
(Type your answer using interval notation. Use a comma to separate answers as needed.)
B. There is no solution.

step-by-step explanation:

actually what is a question i don't understand

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
