What is the range of the function f(x) = 4x + 9, given the domain D = {-4, -2, 0, 2}?

anyanavicka [17]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f( - 4) = 4( - 4) + 9 = - 7$

_________________________________

$f( - 2) = 4( - 2) + 9 = 1$

_________________________________

$f(0) = 4(0) + 9 = 9$

_________________________________

$f(2) = 4(2) + 9 = 17$

_________________________________

Thus ;

R = { - 7 , 1 , 9 , 17 }

The correct answer is (( D )) .

Erin already has 7 plants in her backyard, and she can also grow 2 plants with every seed

Reil [10]

The answer is p=2s+7. Two plants can be grown from each seed packet, and Erin already has seven plants so you add that to the equation as well.

a manufacturer of bicycle parts requires that a bicycle chain have a width of 0.3 inch with an absolute deviation of at most 0.0

quester [9]

Answer:

$|w-0.3| \leq 0.0003$

And solving we got:

$-0.0003 \leq w-0.3 \leq 0.0003$

$0.3-0.0003 \leq w \leq 0.3+0.0003$

$0.2997 \leq w \leq 0.3003$

Step-by-step explanation:

For this case we can define the following notation:

$W$ represent the width

And we want a maximum error of 0.0003 so we can set up the following equation:

$|w-0.3| \leq 0.0003$

And solving we got:

$-0.0003 \leq w-0.3 \leq 0.0003$

$0.3-0.0003 \leq w \leq 0.3+0.0003$

$0.2997 \leq w \leq 0.3003$
