Answer:
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>
Based on the knowledge of a simple quadratic equation (2nd degree), it can have 2 solutions, with one turning point. Following that pattern, we can say that a 6th degree polynomial function has 5 turning points. However, it doesn't have to have 5 turning points, so the correct answer would be "5 or less".
