**Unit 3: Linear and Exponential Functions**Today’s Standard: A.REI.10 “Represent and solve equations and inequalities graphically.”**Essential Question:**• How do I make a table of values and plot the points on a coordinate plane for linear and exponential functions?**Language of the Standard**MCC9-12.A.REI.10: Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a line or a curve.**What we will be doing today:**• Basically you are going to be given a function, (either linear or exponential), and asked to make a table of values, then plot the points on a coordinate plane, and draw a line/curve.**Steps:**• Assign these values for x: -2, -1, 0, 1, and 2 • Solve for y by plugging each value in for x and working the problem out (you will be dealing with fractions so GET EXCITED!!) • Plot the points on a coordinate plane • Draw your line or curve **You will need to remember your negative exponent rules when solving an exponential function**Example 1**y = 2x - 1**Example 2:**3x + 2y = 6**Example 3:**y = 2• 3x**Example 4:**y = ½ • (¼)x**Assignment:**• worksheet
