Note: a graph by itself is not a sufficient justification for your answer. 10. Find the equation of the tangent line to the curve: f (x ) = 247+3 5x at the point where x - 2. Note: you may use technology to do computations, create tables or graphs, and/or check your results. Technology may not be used to do Calculus operations such as derivatives. 1 1. Biologists have proposed a cubic polynomial to model the length L of rock bass at age 4: L = 0.0543 - 0.4A2 + 8A + 1 where L is measured in inches and A in years. Note: you may use technology to do computations, create tables or graphs, and/or check your results. Technology may not be used to do Calculus operations such as derivatives. (a) Find A = 12 (b ) Interpret your answer in part (a) by explaining the meaning in context using a complete English sentence. 12. For g(x) = 6x - 5 and h(x) = =+1 Find and simplify g (h(x2))
