Extensions and Connections (for all students) o Assign students to read “Step 1: Change Your Life with One Calculation: How Compound Interest from Investing Grows Your Money Faster than Anything Else,”. However, changing the value of b causes the graph to change in a way that puzzles many. Jokes Algebra I 1. A quadratic model, for instance, might have been better. Desmos has a nice little feature that allows one to copy an image onto a coordinate grid. Step 2: Sum all x, y, x2 and xy, which gives us Σx, Σy, Σx2 and Σxy (σ means "sum up") Step 3: Calculate Slope m: m = (Nσxy − Σx Σy) N(Σx2) − (Σx)2. Data points are plotted on a graph to represent data and determine correlation. Loading Logistic Regression Drag/Drop. Derivatives of Exp and Logs Desmos In the "notice/wonder" section of f(x)=a^x, one student said he noticed that the derivative was proportional to the given function.
