For the following exercises, use Figure 20 to estimate either the function at a given value of x or the derivative at a given value of x, as indicated.
f′(−1)
Consider the graph given below.
From the graph, the graph becomes vertical as x → -1. Also the value of f → -∞ as x → -1. Hence the slope of the curve at x = -1 is -∞. Therefore, f\'(-1) = -∞.
Hence the slope of the curve at x = -1 is -∞. Therefore, f\'(-1) = -∞.
Hence the slope of the curve at x = -1 is -∞. Therefore, f\'(-1) = -∞.
