Answer:
(0,90)
Step-by-step explanation:
Given data
The function f(x) = 60 + 10x
x= 3 hours
The range is a set of values for f(x) for a corresponding value value for x
f(3) = 60 + 10(3)
f(3) = 60 + 30
f(3) = 90
We can say the domain of her study time is between (0,3) hours
While the Test score is in the range (0,90)
