To find the range of the function $y=7x-1$ when the domain is $\{ -1,0,1\} $, we need to substitute each value from the domain into the function and calculate the corresponding output values.<br /><br />Step 1: Substitute $x=-1$ into the function:<br />$y=7(-1)-1$<br />$y=-7-1$<br />$y=-8$<br /><br />Step 2: Substitute $x=0$ into the function:<br />$y=7(0)-1$<br />$y=0-1$<br />$y=-1$<br /><br />Step 3: Substitute $x=1$ into the function:<br />$y=7(1)-1$<br />$y=7-1$<br />$y=6$<br /><br />Therefore, the range of the function $y=7x-1$ when the domain is $\{ -1,0,1\} $ is $\{-8,-1,6\}$.
