Answer:

○ $\displaystyle yes; k = 4; y = 4x$

Step-by-step explanation:

All you are doing is plugging numbers into each answer choise to determine the equation and constant of variation. When you do, you will arrive at this answer. You could also apply mental mathematics to determine whether or not these chart displays a scale factour of 4, which they do.

PLZ HELP MARKIN BRAINIEST!!!

From the graph, when x = 1, y = 57,000.

Replace x with 1 in the equations and see if any of the Y 's equal 57,000 :

y = -2610.82(1) + 47860.82 = 45,250

y = 219(1)^2 - 6,506.78(1) + 59,385 = 219 - 6506.78 + 59385 = 53,097.22

y = 54041.5(0.9)^1 = 48,637.35

y = 10,504.6 (1.1)^1 = 11,555.06

The second equation is the closest. so try another x value to see if it is close to the Y value:

Let's try x = 14:

y = 219(14)^2 - 6506.78(14) + 59,385 = 42924 - 91094.92 + 59385 = 11,214.08

This is close to Y = 12,00 shown on the graph

SO the closest equitation is y = 219x^2 - 6506.78x + 59385
