A student divided f(x) 3x3 + 8x2 + 5x – 4 by x + 2 and found the remainder was r = -6. Based on the remainder theorem, what can be concluded about f(x)?
The function f(x) = 3x3 + 8x2 + 5x – 4 has a zero at -6.
The function f(x) = 3x3 + 8x2 + 5x – 4 has a zero at -2.
The y-intercept of the graph of f(x) is – 6.
The point (-2,-6) lies on the graph of f(x).

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
