Lesson 4 Prove It Right Practice Understanding

Ready

Find the value of $f (x)$ for the given domain. Write $x$ and $f (x)$ as an ordered pair.

1.

$f (x) = 3 x - 2$

$x$	$f (x)$	$(x, f (x))$
$- 2$
$- 1$
$0$
$1$
$2$

2.

$f (x) = x^{2}$

$x$	$f (x)$	$(x, f (x))$
$- 2$
$- 1$
$0$
$1$
$2$

3.

$f (x) = 5^{x}$

$x$	$f (x)$	$(x, f (x))$
$- 2$
$- 1$
$0$
$1$
$2$

4.

$f (x) = - 2 x^{2} + x + 5$

$x$	$f (x)$	$(x, f (x))$
$- 2$
$- 1$
$0$
$1$
$2$

5.

$f (x) = \frac{1}{2} x + \frac{5}{2}$

$x$	$f (x)$	$(x, f (x))$
$- 2$
$- 1$
$0$
$1$
$2$

6.

$f (x) = {(\frac{1}{2})}^{x}$

$x$	$f (x)$	$(x, f (x))$
$- 2$
$- 1$
$0$
$1$
$2$

Set
