7. Describe the graphs of the following equations. Include a rough sketch of the basic shape of the graph.
A) y = -2sin(x) + 3
B) y = (x - 1)³
8. What type of discontinuity does the function f(x) =
x²-x-12
have at x = 4? If it is a removable
x-4
discontinuity, how could you define a function such that it would be continuous at x = 4?
10. Given the graph shown:
A) Sketch the secant line between x = 1 and x = 4.
Estimate the slope of this secant line.

B) Sketch a tangent line at x = 1.
Estimate the slope of the tangent line.
