For notes ... thank you in advanced

1. Sketch the function below and find and identify the discontinuities in the following function: 3x+1;x3 2. Use the increment method to: Find the slope of the line tangent to y = cosx at (2,1) 3 __ x3 3. Use any differentiation technique to findd dilxbz given y - "2x +1 4. Use any differentiation technique to find d:|x__1 given y= (16x)(\\/- + 2x) 5. Use any differentiation technique to find yl,c_0 given y= 3x - \\le + 1
