1 . The point p ( 3 , 1 ) lies on the curve y = 3 It Q is the point ( x , 3 ), find the slope of the X Secant line PQ when x = 3.001 and x= 2.999 Guess the value of the slope of the tangent line to the curve at p(3, 1 ). 2. Guess the value of each limit by substituting a value for x near a . a ) lim VX +2 d = 2 x a X - 2 b jim Sin X a = 0 x-> a X
