Determine a polynomial equation for a graph that passes through the point (6.-196) and has these three X-
intercepts: (-8, 0), (-1,0), and (5,0).
y= -0.5 (2 - 8) (0 - 1)(2+5)
y=-2(- 8) (x - 1)(x+5)
y=0.64 (2+8) (2+1) (2 - 5)
y=-2 (2x+8) (x + 1) (2-5)

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

step-by-step explanation:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
