Review the table showing the mass of a radioactive isotope over time. Which function best models this data?

y = 11.97(0.93)x

y = –0.42x + 10.75

y = 13.15 – 3.17 ln x

y = 0.01x2 – 0.72x + 11.82

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
