Step 1
It's a piecewise function, which means it's defined by different expressions for different parts of its domain. For x<0, the function is 4x. This is a linear function with a slope of 4, so it will be a straight line going downwards as x approaches 0 from the Show more…

The domain of each piecewise function $i s(-\infty, \infty)$. a. Graph each function. b. Use your graph to determine the function's range. $$f(x)=\left\{\begin{array}{ccc}0 & \text { if } & x<-4 \\-x & \text { if } & -4 \leq x<0 \\x^{2} & \text { if } & x \geq 0 \end{array}\right.$$

The domain of each piecewise function $i s(-\infty, \infty)$. a. Graph each function. b. Use your graph to determine the function's range. $$f(x)=\left\{\begin{array}{ccc}\frac{1}{2} x^{2} & \text { if } & x<1 \\2 x-1 & \text { if } & x \geq 1\end{array}\right.$$
Graph each piecewise-defined function. Use the graph to determine the domain and range of the function. $$ f(x)=\left\{\begin{array}{ll} {-2 x} & {\text { if } \quad x \leq 0} \\ {2 x+1} & {\text { if } \quad x>0} \end{array}\right. $$
