• Hi! I am Zora and this is Jarriah and Elijah. We will be teaching you lessons ﻿44 and 49.
• Lesson 44 is to Distinguish between situations that can be modeled with linear functions and with exponential functions.
• Lesson 49 is to Represent data with plots on the real number line (dot plots, histograms, and box plots.
• ﻿﻿Lets start with lesson 44. What you need to know is that linear functions are functions with a constant rate of change. They are written in the form of y=mx+b.
• Exponential functions ﻿have a slop that is raised to the x power. It looks like y=abx
• The differences between linear and exponential ﻿functions is that ﻿the linear functions are straight lines while exponential functions look like a j-curve. Linear functions are constant. Exponential functions are not.
• For example, the function y=2x+9 is a linear function. The 2x is the rate of change while 9 is the y-intercept.﻿
• The function y = 2x  is an example of an exponential function.
• Now lets do lesson 49. A data plot holds data from a set of numbers. The first one we'll talk about is a dot plot. A dot plot is basically a number line with dots over the numbers depending on the situation.
• A histogram is a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval.
