QuestionDefine the function $f(x)$ as: $f(x)=x$ if $x<0$ and $f(x)=x^{2}$ if $x \geq 0$. Find its domain, intercepts, graph, and range.

Studdy Solution
(d) To find the range of the function based on the graph, we identify the set of all possible $y$ values that the function can take.
Looking at the graph, we see that the function takes all $y$ values greater than or equal to0.
So, the range of the function is $[0, +\infty)$.
