Table \(\PageIndex{1}\) lists the average cost, in dollars, of a gallon of gasoline for the years 20052012. Next use the formula. Likewise, \(f\) has a local minimum at a point \(b\) in \((a,c)\) if \(f(b)\) is less than or equal to \(f(x)\) for every \(x\) (\(x\) does not equal \(b\)) in the interval. For a linear function, the rate of change m is represented in the slope-intercept form for a line: y=mx+b whereas the rate of change of functions is otherwise defined as, (f(b)-f(a))/ b-a, Rate of change = (Change in quantity 1) / (Change in quantity 2), y/ x = \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\). This means that, for every increase in the x-value by 1, the y-value increases .
