Question
Give the domain of the linear equation:

y= x + 2
  _____

   x

Answer
Brandon,

The domain is the set of values that x can take without causing the function to "explode". You can think of it as all possible values that can go into the function.

The only thing we need to watch out for here is that the function will tend toward infinity when x=0.

To prevent this from happening, we remove x=0 from the set of real values. Everything else is legit. So, the domain for this function is everything on the real line, excluding 0.

Expertise

When I work through problems, I like to emphasize concepts which I believe are worth noting. I will try to answer questions in the following areas, but not at the advanced level. Algebra. Sequences & Series. Trigonometry. Functions & Graphs. Coordinate Geometry. Quadratic Polynomials. Exponential & Logarithms. Basic Calculus. Probability, Permutation and Combination. Mathematical Induction. Complex numbers. Physics problems.

Experience

I have worked as a teaching assistant in college. My hope is that more people will share knowledge without boundary, give help without seeking recognition or monetary rewards.
