Basically meaning that no model can exactly be on point with whatever it is modeling. Two things cannot be EXACTLY identical to what they are referring to, but it is saying that some can get close enough to be useful as an example.
A function of the form , where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
Step-by-step explanation:
A linear function is one in which the value of the function varies linearly with 'x'. When we plot a linear function on a graph, the resulting curve is always a straight line with the slope of the line being constant.
A linear function is of the form:
, where, 'm' and 'b' are real numbers.
The degree or the highest exponent of 'x' in a linear function is always equal to 1.
Therefore, a function of the form , where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
