Answer:
a) Table and graph showed
b) The distance will be 231 miles
c) Yes
Step-by-step explanation:
We know the van gets 22 mi/gal, so the distance D in miles traveled by the van can be expressed as
D(g)=22g, being g the number of gallons of gas used
a) The graph of the function D and its corresponding table of values is shown below.
b) If the van used g=10.5 gallons of gas, the distance would be:
D(10.5)=22 x 10.5 = 231 miles
c) The values of g are real in nature because they represent the amount of gas consumed by the van and it can be any real positive number. Being D a linear function of g, it also happens to take positive real values. Then it makes sense to connect the points with lines.
The given equation is :
1. The relationship such that dependent variable (y) is isolated is :
2. The table accompanying this equation :
- x = -4 and y = 0.5
- x = -1 and y = 2
- x = - 0.5 and y = 4
- x = 0 and y = undefined
- x = 0.5 and y = -4
- x = 1 and y = -2
- x = 4 and y = -0.5
3. graph of the given equation is in attachment ~
