Answer:
Step-by-step explanation:
Given the equation of the weight of an empty shipping box expressed as:
100t + 300 = w
We are to select all possible solutions for (t,w) to the equation 100t + 300 =w. From the equation the input variable is t which serves as the DOMAIN while the output variable is w which serves as the RANGE. To get the possible of t, we will need to find the values of t that will make the function to exist. Since the number of t shirts are always positive, this means that the value of t exists on all positive real numbers. Hence the Domain is expressed as:
Domain: [0, ∞)
Since the weight w must also be positive, the lowest value of w we can get it at when t = 0. Substitute into the equation:
100t + 300 =w
100(0) + 300 = w
300 = w
w = 300
Hence the minimum output (weight) that we can have is 300, the Range of the expression will be expressed as:
Range: [300, ∞)
