Sketch a graph of the function. Given the piecewise definition $f(x) = \begin{cases} -2x-4 & \text{if } x \le -1 \\ x & \text{if } x > -1 \end{cases}$ Draw the graph of $f$. Domain: (-∞,∞) Range: (-∞,∞)

Step 1
For $x \le -1$, the function is $f(x) = -2x-4$. This is a linear function with a slope of -2 and a y-intercept of -4. Show more…

Graph each piecewise-defined function. Use the graph to determine the domain and range of the function. $$f(x)=\left\{\begin{array}{lll} {4 x-4} & {\text { if }} & {x<2} \\ {-x+1} & {\text { if }} & {x \geq 2} \end{array}\right.$$

Graph each piecewise-defined function. Use the graph to determine the domain and range of the function. $$f(x)=\left\{\begin{aligned} x+3 & \text { if } \quad x<-1 \\ -2 x+4 & \text { if } \quad x \geq-1 \end{aligned}\right.$$
Sketch a graph of the piece wise defined function. $$f(x)=\left\{\begin{array}{ll} 2 & \text { if } x \leq-1 \\ x^{2} & \text { if } x>-1 \end{array}\right.$$
