3. Consider the usual exponential function f(x) = e. (a) Without using a calculator, use linear approximation to estimate e-0.015 Express your answer as a fraction of two integers. Hint: What is f(x)? What is the "anchor point" = a? What is the point zo at which we are approximating? -0.015 (b) Without using a calculator, determine if your answer in (a) is an overestimate or an underestimate. Circle the best answer choice and justify your answer. Feel free to give a graphical representation. UNDERESTIMATE OVERESTIMATE (c) Use a calculator to find the absolute error Efo(-0.015) that results from using the linear approx- imation to estimate e-0.015.
