Given:
The expression is
To find:
The value of given expression.
Solution:
We have,
BODMAS : Bracket, Order, Division, Multiplication, Addition, and Subtraction.
Using BODMAS, first we need to perform division in the given expression.
Now, apply addition.
Now, apply subtraction.
Therefore, the value of given expression is 1.
The domain is the set of allowed x inputs, or x coordinates of a function. In this case, any point on the curve has an x coordinate that is 4 or smaller.
Therefore, the domain is the set of numbers x such that
To write this in interval notation, we would write This interval starts at negative infinity and stops at 4. We exclude infinity with the curved parenthesis and include 4 with the square bracket.

The range is the set of possible y outputs. Every point on this curve has a y coordinate that is either 0 or it is larger than 0.
The range is the set of y values such that
In interval notation, it would be written as This time we start at 0 (including this endpoint) and "stop" at infinity
note: we always use curved parenthesis at positive or negative infinity because we cannot reach either infinity
