Henry has a part-time job selling computers. He works 6.5 hours each day,
• The function p(x) = 65 + 25x models his daily earnings, where x is the number
sells during the day.
• Henry sells 3 to 10 computers per day.
Which interval contains all of the values in the range of the function
(A) 3 5 p(x) S 10
(В
10 s p(x) S 185
C
75 s p(x) S 250
D) 140 S P(x) S 315

Answer 1

D) 140 ≤ p(x) ≤ 315

Explanation:

Domain

• Henry sells 3 to 10 computers per day
• 3 ≤ x ≤ 10

Range

• To find the range, input the values of the domain of the function
• p(3) = 65 + 25(3)
• p(3) = 65 + 75 = 140
• p(10) = 65 + 25(10)
• p(10) = 65 + 250 = 315
• Range ⇒ 140 ≤ p(x) ≤ 315

Answer 2

function : p(x) = 65 + 25(x)

for 3 sells

• p(3) = 65 + 25(3)

• p(3) = 140

for 10 sells

• p(10) = 65 + 25(10)

• p(10) = 315

So,

140 ≤ p(x) ≤ 315
