Question

A function of the form f(x) = mx + b, where m and b are real numbers, is called a _____

Answer 1

A function of the form
`f(x) = mx + b`, where 'm' and 'b' are real numbers, is called a linear function.

Explanation:

A linear function is one in which the
`f(x)` 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:

`f(x)=mx+b`, 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
`f(x) = mx + b`, where 'm' and 'b' are real numbers, is called a linear function.
