Answer:
The range is the output value or the y value.
You would work backwards to find the domain.
f(x) = 4x - 1 f(x) = 4x - 1
3 = 4x - 1 7 = 4x - 1
add 1 to both sides add 1 to both sides
4 = 4x 8 = 4x
divide both sides by 4 divide both sides by 4
x = 1 x = 2
f(x) = 4x - 1 f(x) = 4x - 1
11 = 4x - 1 15 = 4x - 1
add 1 to both sides add 1 to both sides
12 = 4x 16 = 4x
divide both sides by 4 divide both sides by 4
x = 3 x = 4
Domain { 1, 2, 3, 4}

Answer:
2 hours 1 minute 9.23 seconds
Step-by-step explanation:
Since they are traveling in opposite directions, their separation speed is the sum of the magnitudes of their speeds: 30 +22 = 52 mph.
The time is related to speed and distance by ...
time = distance / speed
= (105 mi)/(52 mi/h = 2 1/52 h ≈ 2 h 1 min 9.23 sec
It will take a little over 2 hours before they are 105 miles apart.
