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:
The median is 30
Step-by-step explanation:
The median is basically calculating the numbers before you, in median you need to find the middle value number. And its 30.
Answer:
Step-by-step explanation:
The length of a rectangle is three times the width. Find the width if the perimeter is 80 cm.
PERIMETER = 2L +2W
L=3W
PERIMETER= 2(3W) +2W
80= 6W +2W =8W
80=8W
W=10
L=3X10=30

(2x10) + (2X30) =20+60=80
