Question

Which graph shows the equation V = 4 + 2t, where V is the total volume of water in a bucket and t is the elapsed time in minutes? Mark this and

Answer 1

1. Subtract 4 from both sides
v - 4 = 2t
2. Divide both sides by 2
v - 4/2 = t
3. Switch sides
t = v - 4/2

Answer 2

we have

$V=4+2t$

where

V--------> s the total volume of water in a bucket

t-------> is the elapsed time in minutes

we know that

The domain of the function is the interval----------> [0,∞)

Because the time (t) can not be negative

The range of the function is the interval---------->  [4,∞)

Because the Volume (V) can not be negative

using a graph tool

see the attached figure

therefore
