Functions to KnowCurrent LectureIII. Graphing ExamplesA. 2 bicycles are going at constant speeds. One is going at 3 m/s and the other at 5 m/s. The first bicycle has a 10 m headstart at t=0. When will their paths cross?1. Graph the two lines2. Set up the equation with the y intercept (10 for the first bike)3. Determine the intersection point4. Slope = units of the y axis/units of the x axisB. If two slopes intersect and one is a positive constant speed and the other is a negative constant speed, they are moving in opposite directions.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.IV. Know these functions:A. Proportions: y = mxB. Linear: y= mx + bC. Inverse: y = A/xD. Top opening parabola: y=Ax^2E.
