This lesson will cover how to write piecewise functions in terms of the Heaviside step function, and then find the Laplace transform and inverse Laplace transform of piecewise functions. Identify whether or not the graph is a function and if it is continuous. plot(x, map(f, x)) The map function takes a function f, an array x and returns another array where the function f is applied to each element of the array. To be differentiable at a point x = c, the function must be continuous, and we will then see if it is differentiable. A piecewise function is a function that combines two or more functions. So you did copy the question wrong; it didn't state that f is continuous, but asked whether it is! There is no piecewise function in this problem; the answer is simply that it is not continuous, because it is not even defined at x=2. ° ® °¯ t 5 if 2-4 if 2 xx fx x 2. Groups create an absolute value graph using a table, then entertain the idea of an absolute value function defined as two pieces The function whose graph is given above is not continuous but it is piecewise continuous because it consists of three continuous pieces separated by ﬁnite discontinuities. 1) f (x) = {x2 + 2x + 1, x < 1 − x 2, x ≥ 1 x f −6 −4 −2 2 4 6 8 −6 −4 −2 2 4 6 8 (−∞, 1), [ 1, ∞) 2) f (x) = {1, x ≠ 5 3, x = 5 x f −2 2 4 6 8 10 12 −6 −4 −2 2 4 6 8 10 (−∞, 5), ( 5, ∞) Find the intervals on which each function is continuous.
