a practice 5. shopping you are buying orange juice for $4.50 per container and have a gift card worth $7. the function f(x)=4.50x - 7 represents your total cost f(x) if you buy x containers of orange juice and use the gift card. how much do you pay to buy 4 containers of orange juice? stem 6. physics light travels about 186,000 mi/s. the function d(t)=186,000t gives the distance d(t), in miles, that light travels in t seconds. how far does light travel in 30 s? problem 4 finding the range of a function got it? the domain of g(x)=4x - 12 is {1, 3, 5, 7}. what is the range?

Answer

5.

Explanation:

Step1: Substitute x value

Substitute $x = 4$ into $f(x)=4.50x - 7$. $f(4)=4.50\times4 - 7$

Step2: Calculate multiplication

$4.50\times4=18$. So $f(4)=18 - 7$

Step3: Calculate subtraction

$18-7 = 11$

Answer:

$11$

6.

Explanation:

Step1: Substitute t value

Substitute $t = 30$ into $d(t)=186000t$. $d(30)=186000\times30$

Step2: Calculate multiplication

$186000\times30 = 5580000$

Answer:

$5580000$ miles

Problem 4

Explanation:

Step1: Substitute domain values

For $x = 1$: $g(1)=4\times1-12=4 - 12=-8$ For $x = 3$: $g(3)=4\times3-12=12 - 12 = 0$ For $x = 5$: $g(5)=4\times5-12=20 - 12 = 8$ For $x = 7$: $g(7)=4\times7-12=28 - 12 = 16$

Answer:

${-8,0,8,16}$
