domain of (2x+1)/(3x)
⚠ 2x is read as the product 2*x: for a power, write 2^x‖3x is read as the product 3*x: for a power, write 3^x
Let's evaluate the domain of 2x + 13x
For the expression 2x + 13x to exist, you must check: 3x ≠ 0
The expression can be simplified by: 3
Solution obtained: x ≠ 0
▶Domain of definition:   x ∈ ℝ \ {0}
