f(x)=1+x^2
find domain and range of the function
You asked:
Find the domain and the range of \(f\left( x \right) = 1 + {x}^{2}\)
MathBot Answer:
Domain
Set notation:
\(\displaystyle\mathbb{R}\)
Interval notation:
\(\displaystyle\left(-\infty, \infty\right)\)
Range
Set notation:
\(\displaystyle\left\{f \in \mathbb{R}:f \geq 1\right\}\)
Interval notation:
\(\displaystyle\left[1, \infty\right)\)
