Write the equations of the following.
a. A line with slope 3 and y-intercept 5.
b. A circle of radius 4 centered on the point (5,-3)
c. A line with slope -3 which passes through the point (-2,1)
What type of symmetry do each of the following equations have? (even, odd, or neither). If there is symmetry, what is the equation of the axis of symmetry? Plot each of the equations and the axis of symmetry (or to show that it has no axis of symmetry) to verify your answer.
a. y = (x - 5)(x + 5)
b. y = x3 - x2 -2x + 1
c. y = x3 - x
d. y = x2 -2x + 6
e. y = |2x + 1|
Given the following function : y = f(x) = 3x + 2
How can the following shifts and scale changes to get
a. y1 = f(x) -2
b. y2 = f(x-2)
c. y3 = 2f(x)
d. y4 = f(3x)
e. y5 = f(x) * f(x)
