Question

simplifyyyyyy!!!! f(X)=(3x^2-4x+1)/(3x-1)
sing complete sentences, explain why f(1) = 0, f(0) = –1, and f(–1) = 2, yet f(1/3) is undefined. Make sure to show your work.

Answer 1

f(x) is short for the complicated expression (3x^2-4x+1)/(3x-1)
It saves typing.
f(1) means replace all the x's with 1's. Then do the arithmetic.
can you replace x with 1 in
(3x^2-4x+1)/(3x-1)
?

you would get
(3*1^2 -4*1+1)/(3*1-1)
(remember, for example, 3x is short hand for 3 times x. when x is 1, this becomes 3*1)
1^2 (one squared) is short for 1 times 1 or 1*1

Can you simplify by doing the arithmetic?
