Question

complete the table.
$f(x) = -2x - 34$

$x$	$f(x)$
$-1$	$square$
$1$	$square$
$3$	$square$

Explanation:

Step1: Substitute x = -3 into f(x) = -2x - 34

$f(-3) = -2\times(-3) - 34 = 6 - 34 = -28$

Step2: Substitute x = -1 into f(x) = -2x - 34

$f(-1) = -2\times(-1) - 34 = 2 - 34 = -32$

Step3: Substitute x = 1 into f(x) = -2x - 34

$f(1) = -2\times1 - 34 = -2 - 34 = -36$

Step4: Substitute x = 3 into f(x) = -2x - 34

$f(3) = -2\times3 - 34 = -6 - 34 = -40$

Answer:

When $x = -3$, $f(x) = -28$; when $x = -1$, $f(x) = -32$; when $x = 1$, $f(x) = -36$; when $x = 3$, $f(x) = -40$. So the completed table (from top to bottom in the $f(x)$ column) has values -28, -32, -36, -40.
