Below is the the graph of a function f(x) and the graph of a linear function L(x). ) Use a secant line approximation to estimate f(3). -) Is your answer

in part (a) an underestimation or an overestimation?. :) Put the following quantities in ascending order, with "<" or "=" between them.(For example, your answer could look like A < B = C < D. Use the boxes for < and = and the blanks for the letters. ) \text { A. } f^{\prime}(2) \lim _{x \rightarrow 4} \frac{f(x)-f(4)}{x-4} \lim _{x \rightarrow 4} \frac{L(x)-L(4)}{x-4} \lim _{h \rightarrow 0} \frac{f(1+h)-f(1)}{h}
