Answer: The exponent of a linear function is always 1.
Explanation:
In mathematics, a linear function is defined as a function that can be represented by a straight line on a graph. The general form of a linear function is y = mx + b, where "m" represents the slope of the line and "b" represents the y-intercept. The exponent of a variable in a linear function is always 1, as there is no exponent applied to the variable.
