A. 7log2x -log2(x + 2) B. log2(x + 2) - 7log2x C. log2(x + 2) + 7log2x D. log2(x + 2) -log2x
Provide an appropriate response. Is the statement true or false?3x3 + 2x4 = 5x7
A. False B. True
Provide an appropriate response.Consider the functions f(x) = x2 and g(x) = x3 and their linearizations at the origin. Over some interval 
the approximation error for g(x) is less than the approximation error for f(x) for all x within the interval. Derive a reasonable approximation for the value of ?. Show your work. (Hint, the absolute value of the second derivative of each function gives a measure of how quickly the slopes of the function and its linear approximation are deviating from one another.)
