determine the domain and range of f(x)=3x/(x+3)
You asked:
Find the domain and range of \(f(x)=\frac{3 x}{x + 3}\).
MathBot Answer:
Domain
Set notation:
\(\displaystyle\left\{x \in \mathbb{R}:x \neq -3\right\}\)
Interval notation:
\(\displaystyle\left(-\infty, -3\right) \cup \left(-3, \infty\right)\)
Range
Set notation:
\(\displaystyle\left\{f \in \mathbb{R}:f \neq 3\right\}\)
Interval notation:
\(\displaystyle\left(-\infty, 3\right) \cup \left(3, \infty\right)\)
