Web1.3 Rate of Change and Initial Value There are a couple of very important numerical (or quantitative) qualities of functions that we use. We like to know where functions start (initial value) and how steep they go up or down from there (rate of change). ... calculate the average rate of change given the table or word form of a function. WebWhen a linear function is given by the equation of a line of the form y = mx +c, the rate of change is m and initial value is b. Both are easy to identify. The rate of change of a linear function is the slope of the line it represents. It is the change in the values of y per a one unit increase in the values of x.

WebLinear Function. A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line. f(x) = mx + b. where b is the initial or starting value of the function (when input, x = 0 ), and m is the constant rate of change, or slope of the function. The y-intercept is at (0, b). WebDec 27, 2024 · The rate of change formula is used to find the rate of change of two variables.
