Approximating slopes of tangent lines using the process shown last week for the function f(x) =3-x2 at the point (2, -1). Using a straightedge, draw a tangent line as accurately as possible at
the point (2, -1). Then draw a secant line through the points (2, -1) and (3, -6). We will refer to that as the right secant line. Draw another secant line, this time through the points (1, 2) and (2, -1). This is the left secant line. Answer the following questions.
2. What is the slope of the right secant line?
