Given:

The function is

f(x)=4x+9

Domain = {-4, -2, 0, 2}

To find:

The range of the given function for the given domain.

Solution:

We know that domain is the set of input values and range is the set  of output values.

We have, f(x)=4x+9 and domain = {-4, -2, 0, 2}.

Putting x=-4 in the given function, we get

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

f(-4)=-16+9

f(-4)=-7

Putting x=-2 in the given function, we get

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

f(-2)=-8+9

f(-2)=1

Putting x=0 in the given function, we get

f(0)=4(0)+9

f(0)=0+9

f(0)=9

Putting x=2 in the given function, we get

f(2)=4(2)+9

f(2)=8+9

f(2)=17

The output values are -7, 1, 9, 17. So, the range of the function f(x) for the given domain is {-7, 1, 9, 17}.

Therefore, the correct option is D.

You paint 1/2 wall in 1/4 hour. At that rate, how long will it take you to paint one wall?
Mnenie [13.5K]
(1/2) / (1/4) = 1 / x......1/2 wall to 1/4 hr = 1 whole wall to x hrs
cross multiply
(1/2)(x) = (1/4)(1)
1/2x = 1/4
x = 1/4 * 2
x = 2/4 reduces to 1/2....so it will take 1/2 hr (or 30 minutes) to paint the whole wall.

zvonat [6]

Answer:

Step-by-step explanation:

Answer: Divide Kayak budget by rental rate

Step-by-step Explanation:

As Joshua is renting for himself alone, the two available options would be the Single Kayak and the Single Sea Kayak.

He can determine the number of hours to rent a Kayak for by dividing his Kayak Budget by the rental rate per hour of the 2 options available to him.

Single Kayak

Budget available = $50

Rental rate = $15 per hour

Hours he can rent = 50/15

= 3.33 hours

Single Sea Kayak

Budget available = $50

Rental rate = $18 per hour

Hours he can rent = 50/18

= 2.78 hours
