Question 1

Use the derivative formula below to compute the derivative of f(x) = x2 + 3x. SHOW WORK. You may want to review my announcement in Canvas about "Evaluating a Limit: What My Work Should Look Like" before answering this question. Recall that, f'(x)= lim flx+h)_") \"-50 h The annual net income for Sky High Electric Company for the period 20072011 could be approximated by the function P(t)= 31'2 _ 24.]?4. 60 billion dollars (2 5 t g 5), where t is the time in years since 2005. Use this function to answer the questions below. Use the symmetric difference quotient (SDQ) to estimate the value of [1(3), using h = 0.0001 in the formula below. Include units with your answer. SHOW WORK in computing your value for work. Recall that, P(3+h)P(3h) SDQ: 2h Interpret the value of [7(3) that you computed above. Your interpretation should have 3-parts as discussed in class and on the document about interpreting a derivative in the Files area of Canvas. Combine all three parts of yourinterpretation into a single sentence. If you were unable to compute a value in the last problem use 80.6 (which is not the answer to the previous question) for the value of P'(3) in this part. Enter your sentence in the textbox below. Your sentence should be free of mathematical jargon
