Many diabetics need to control their blood sugar levels with insulin. A graph is given that shows blood sugar levels over time after insulin is given to a non-diabetic person at time, t = 15 minutes. As you can see insulin causes blood sugar levels to drop. Where is the function not differentiable and why? Blood Sugar Levels Time 0 The function is differentiable everywhere except t = 30. O The function is differentiable everywhere. O The function is differentiable everywhere except t = 15, t = 30, and t = 40 where there are corners. O The function is differentiable everywhere except at t = 15 where there is a discontinuity. Water changes chemical structure as it is heated. It goes from ice, to liquid, to boiling. This is called a phase change. The graph given shows how the temperature of water changes as it is heated. You can identify phase changes on a graph by finding places where the change in temperature over time (derivative) is very small or zero. Where are the phase changes in the graph below? Temp 100 2:88 Temperature 10 15 20 25 30 35 40 45 50 Time O At times t = 35 to t = 45. O At times t = 15 to t = 35 and from t = 45 to t = 50. O At times t = 0 to t = 10 and from t = 25 to t = 35. O At times t = 25 to t = 30 and from t = 45 to t = 50.f (x) = lim f(xth )-f(x) h-0 h iff (x) = Ixl. Use the definition of the derivative to determine if the function is differentiable at x = 0. f (X) is not differentiable at x = 0 because the lim f (xth)-f(x) increases without bound at x = 0. h -c h o f (x) is not differentiable at x = 0 because the lim f(xth)-f(x) h -c h is not the same from the right and left. o f (x) is not differentiable at x = 0 because the lim f(xth)-f(x ) = 0 at x = 0. h-0 h o f (x) is differentiable at x = 0.\fWhere is the graph shown not differentiable and why?
