PLZ HELP ME!!! Use cubic regression to find a
function that fits the following
points.
(1,-9), (2,-15), (3,-29),(-1,3)
y = -x3+ [? ]x2 + []x + [ ]

(I tried asking for help with this before but someone just took the points and didn’t answer!)

i will pick c put check it over to be sure

step-by-step explanation:

if x = 1, then the answer is 3.5

b is the correct answer

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
