How to do rate of change.

The general form of an equation in point-slope form is y - y1 = m (x - x1) where m is the slope and (x1,y1) is the point. Our point is (7,109.45) and the slope is the average slope between [6.5,7.5] which is 1.9. Plug these into the equation and you get an approximation of the equation of a tangent line at (7,109.45).

Method 2. Step 1: Divide the New Value by the Old Value (you will get a decimal number) Step 2: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) Step 3: Subtract 100% from that. Note: when the result is positive it is a percentage increase, if negative, just remove the minus sign and call it a decrease. If f f is a function of x x, then the instantaneous rate of change at x = a x = a is the limit of the average rate of change over a short interval, as we make that interval smaller and smaller. In other words, we want to look at. limx→a Δf Δx = limx→a f(x) − f(a) x − a. lim x → a Δ f Δ x = lim x → a f ( x) − f ( a) x − a.
