Question

(2x^2+3x+1)/(2x+1) Using complete sentences, explain why f(1) = 2, f(0) = 1, and f(–1) = 0, yet f(–) is undefined. Make sure to show your work.

Answer 1

yet f(-1/2) is undefined **

Answer 2

because when x = -1/2, the denominator will be 0... how do you divide by zero?

Answer 3

ok and you have to simplify the f(x) = (2x^2+3x+1)/(2x+1)

Answer 4

and show your work ..

Answer 5

simplified, f(x) = x+1. Just factor the top to (2x+1)(x+1).

Answer 6

restriction?

Answer 7

x is not equal to -1/2

Answer 8

can you help me on my other question

Answer 9

sure

Answer 10
