This is for my notes please :)

1. Sketch the function below and nd and identify the discontinuities in the following function: -3x+1;x3 :x22 2. Use the increment method to: Find the slope of the line tangent to y = cosx at ($0) 3 3 . . . . _ d _ 72: 3. Use any differentiation technique to find 3y lag.2 gwen y = 2x\" 4. Use any differentiation technique to find E [H given y = (16x) (J? + 2):)4 dx 1" 5. Use any differentiation technique to find :17: given y = 3x sz + 1
