3.5 Homework For #'s 1 and 2, findthe limit. For numbers 3-6 determine if the function is continuous at the given value of x. If it is not continuous, identify which part of the definition of continuity is not satisfied. x' + 4x + 4, x5-3 x5 2 1) lim f(x), f(x) = 2) lim f(x), f(x) = 10, *- -3+ X x-+2 - -x + 2, x>2 2 2' x> -3 3) lim f(x), f (x) = -2x + 7, x53 x2 - 2x + 1, x3 4) lim f(x), f(x) = * - 0 - + - x20 2 2' -x2 - 4x - 4, x 3 (x + 2, x>-3 Evaluate each limit using direct substitution. 7) lim (-x3 + 3x2 + 1) x-+2 8) lim x - x - 6 *+-1 x +2 9) lim -csc (x) 10) lim V2x + 1 1 1) lim -5 x - -3 12) Find all points of discontinuity for the given function ,x
