Question

Elena works at least 4 hours but not more than 8 hours. the amount of money elena earns for working t hours is represented by a function. p(t)=9.5t what is the practical domain of the function? all real numbers from 4 to 8, inclusive. all integers from 4 to 8, inclusive. all real numbers. all multiples of 9.5 between 38 and 76, inclusive

Answer 1

Answer:

all real numbers from 4 to 8, inclusive

Step-by-step explanation:

Answer 2

Let

t-------> the number of hours

P(t)----> the amount of money Elena earns

we know that

$P(t)=9.5t$

$t\geq 4\ hours$

$t \leq 8\ hours$

so

$4\ hours \leq t \leq 8\ hours$

The practical domain of the function is the interval----> $[4,8]$

that means

all real numbers from  $4$  to  $8$ , inclusive

therefore

the answer is the option

all real numbers from  $4$  to  $8$ , inclusive
