The domain and range of the given function both are the real numbers.
<h2>Given that:</h2>
- The domain and range of function f(x) = 3x + 5 has to be found.
<h2>Explanation for domain and range:</h2>
Considering working in real numbers, domain is 
and range is too.
Domain can be complex numbers too, but for the sake of daily life cases, we consider working in real numbers.
Thinking of it as equation of straight line can help.
The given function is monotonically increasing and continuous.
Thus Range can be calculated as interval ( f(min value of domain), f(max value of domain) ) which gives us as range.
Below is the plot of f(x) = 3x + 5 in real number plane.
In fact, any linear equation of the form
has both domain and range as real numbers.

Answer:
263100=2.63
Step-by-step explanation:
263100 is already in the simplest form. It can be written as 2.63 in decimal form (rounded to 6 decimal places).
Given :
a paddle boat travels upstream = 12 miles
a paddle boat travels downstream = 20 miles
speed of the current = 2 miles per hour
Let the speed of the boat =x
Let the time taken = t
We know the distance for upstream D= (boat speed - current speed) * time
the distance for downstream D= (boat speed + current speed) * time
Plug in all the values and variables in the distance
For upstream 12 = (x-2)t, then 
For downstream 20 = (x+2)t then 
we got two equations for t, equate it and solve for x
Cross multiply it
12(x+2) = 20(x-2)
12x + 24 = 20x - 40 (subtract 12x and add 40 on both sides)
64 = 8x
x= 8
the speed of the boat in still water = 8 miles per hour
