The number of hours that 20 people spent watching television per day, in relation to age, is graphed. This quadratic equation represents the model for the set of data. y = 0.004x^2 - 0.314x + 7.5 Based on the model, approximately how much time does an 18-year-old spend watching television each day?

A. 2 hours

B. 3 hours

C. 7.5 hours

D. 0.5 hours

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

it would take 7/10 of an hour too fill the pool.
