Which of the following equations has roots x = 3 (multiplicity 3) and x = -i? A. f(x) = x3 – 3x2 + x - 3 B. f(x) = x3 + 9x4 + 28x3 + 36x2 + 27x + 27
C. f(x) = x3 – 9x4 + 28x3 – 36x² + 27x – 27
D. f(x) = x3 + 3x2 + x + 3

the answer to this question is 3/19

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
