Question

Hannah painted a 50 square foot wall in her home. The graph shows the remaining Square feet to paint as a linear function of X, The number of minutes spent painting. what is the domain and range of the function?

Answer 1

Domain: 0 ≤ x ≤ 25

Range: 0 ≤ y ≤ 50 where y = f(x)

Explanation:

Domain is the set of all x values. Here x is the number of minutes spent painting and we can see its minimum value is y=0, maximum value is y=25 os domain of function is 0 ≤ x ≤ 25

Range of a function is the set of values of the function ie the outputs produced the function.

Let y = f(x) Then the y values range from minimum of y = 0 to maximum of y = 50. So range is 0 ≤ y ≤ 50 which is 0 ≤ y ≤ 50
