Question
Make a table listing ordered pairs for each function. Then sketch the graph and state the domain and range. Identify any intervals on which $f$ is increasing, decreasing, or constant.$$f(x)=-3 x$$
Step 1
We can choose any values for $x$, but for simplicity, let's choose $x=0$ and $x=1$. When $x=0$, $f(x)=-3(0)=0$. When $x=1$, $f(x)=-3(1)=-3$. So, our table of ordered pairs is: | x | f(x) | |---|------| | 0 | 0 | | 1 | -3 | Show more…
