Question

Simplify f(x) = the quantity 4 x-squared plus 7x minus 2 all over 4x minus 1


Using complete sentences, explain why f(1) = 3, f(0) = 2, and f(-1) = 1, yet f(one-fourth) is undefined. Be sure to show your work.

Answer 1

\[\Large f(x)=\frac{4x^2+7x-2}{4x-1}\]
Is this your question?

Answer 2

Yes.

Answer 3

f(1)=3, f(0)=2 and f(-1)=1
These can be proved by putting the respective values of x in f(x).
Do you get my point?

Answer 4

Yes I understand.
