Answer:
x = 8
Step-by-step explanation:
Given f(x) = 4
The required value of x is from the domain.
The given value of 4 is from the range.
From the diagram
8 → 4
Thus f(x) = 4 when x = 8
1 meter = 1000 mm
so then 5 meters is just 5 * 1000 = 5000 mm.
Rate * time = distance traveled
55 * 4 = 220 miles
