Determine if the given function is continuous or not, using 3 steps. a. f(x) = x4 - 3x3 + 2x? – 5x – 7 at x = -1 %3! b. f(x) = x-3 at x = -3 %3D c. f(x) : x2 at x = 1 x-2 d. f(x) = 2x at x = 4 !! x2-3 e. f(x) = V3x 10 at x = 2 Sample three steps: 2.) Determine if the /(x) = x +1 is continuous at x = 1. Solution: f(1) = 1+1 = 2. lim (x + 1) = 1 +1 = 2. lim f(x) 2 f(1). So fis defined at x = 1. Step 1. Step 2. So lim f(x) exist. M11 Step 3. So f(x) is continuous at x = 1. %3D %3D Determine if the given function is continuous or not, using 3 steps. a. f(x) = x4 - 3x3 + 2x? – 5x – 7 at x = -1 %3! b. f(x) = x-3 at x = -3 %3D c. f(x) : x2 at x = 1 x-2 d. f(x) = 2x at x = 4 !! x2-3 e. f(x) = V3x 10 at x = 2 Sample three steps: 2.)
