Question

complete the table and then graph the function.
$f(x)=2x + 20$

$x$	$f(x)$
-8
-6

click to select points on the graph.

Explanation:

Step1: Substitute $x=-9$ into $f(x)$

$f(-9)=2(-9)+20=-18+20=2$

Step2: Substitute $x=-8$ into $f(x)$

$f(-8)=2(-8)+20=-16+20=4$

Step3: Substitute $x=-6$ into $f(x)$

$f(-6)=2(-6)+20=-12+20=8$

Step4: Identify graph points

The points to plot are $(-9, 2)$, $(-8, 4)$, $(-6, 8)$; the line extends through these points following $f(x)=2x+20$.

Answer:

Completed table:

$x$	$f(x)$
$-8$	$4$
$-6$	$8$

Graph points to plot: $(-9, 2)$, $(-8, 4)$, $(-6, 8)$; draw a straight line through these points representing $f(x)=2x+20$.
