QUESTION 1 0.1 points Saved For questions 1-6, consider the quadratic function f(x) = 2.5x2 - 5 Using the definition of derivative (i.e. the one with limits), what is the derivative of this function, f (x)? labcorp QUESTION 3 0.1 points Saved Using the slope of the tangent line to predict the change in f(x). F'(x). what is your prediction of f() if you increase x by 2, i.e. Ax = h = 2? 0 QUESTION 5 0.1 points Save Answer What is your prediction error from using the tangent line? (Ignore the minus sign, just write the absolute value of the difference.) 2.5 QUESTION 6 0.2 points Save Answer What is your prediction error if you analyze a smaller change in X of 1, i.e. 4x = h = 1? To calculate this, repeat the last three steps for h = 1. You should see that the prediction error is smaller since the derivative is more accurate for smaller changes in X. (Include all decimal places, do not round.)
