Question 3 1 pts If f (x) = 1', then the slope in of the tangent at a point P (a, a? ) is equal to Question 4 1 pts To save time: If you have multiple points on the curve (of f) that you want to calculate the slope of the tangent, it is better that you calculate the slope of the tangent at a point P (a, f (a)) on the curve, then substituting a by the x-coordinate of each point to find the slope of the tangent. True False Question 5 1 pts In the example: f (x) = _, in the process of finding the slope of the tangent at P (3, 1), we encountered the limit of a complex fraction of the type ". What did we do to simplify the limit of this complex fraction? We multiply the numerator and denominator of the complex fraction by the LCD of all terms in the numerator and denominator. We multiply the numerator and denominator of the complex fraction by the LCD of terms in the denominator. We then conclude that the limit DNE
