1. Graph the Following Equations. They are relationships between two variables, x and y, and they are all linear.
a. y = 3 x + 2 |
b. y = 6.85 x + 1.98 |
c. y = -4.2 x + 3 |
d. 3.1 y = x - 7.8 |
e. 2 y = 3 x + 12 |
2. For each of the following graphs determine if the slope of the line is positive or negative. Which graph has a slope of zero?
1. For each of the following graphs determine the period of the repeating function.
2. Based on your understanding of the trigonometric
functions, would you say that the sine and cosine functions are preiodic
or not? Explain. For extra practice try graphing
a function like: y = sin (x).
For each of the 4 colored graphs graphs: 1, 2, 3 and 4, determine whether the exponent is positive or negative.
