Question
Sketch the graph and give the domain and range of the function.$$f(x)=\left\{\begin{array}{cl}4-2 x, & x \leq 2 \\x-2, & x>2\end{array}\right.$$
Step 1
It is a piecewise function, which means it is defined by different expressions depending on the value of x. For x less than or equal to 2, the function is defined as 4 - 2x. For x greater than 2, the function is defined as x - 2. Show more…
