Question

Below are eight functions. Find the first derivative of each. Space is provided. Use good dark ink if you are returning this by a scanned version. All of the derivatives can be found by using combinations of the constant rule, power function rule and sum-difference rule. Do not use the product rule. It is not needed. The degree of difficulty (more or less) increases from (a-h). Be sure to show intermediate work. Check the scoring rubric to see how the points are awarded. For example, the first derivative of the function: 's (2x +3)2 is dY MV dX 2(2x + 3)(2) Although this can be simplified to: please do not simplify your answer. I can better diagnose your differentiation difficulties. This also avoids more atgebrate mistakes on your part. Hint: To make either (g) or (h) easier, multiply the two parts together first, then find the derivative of the resulting product. T avoids the need to use the product rule. Good Luck! a) D 60-20+180 d) W 3x4+2X-4X dW/dX- dD/dQ

Explanation / Answer

a)

D = 6Q^4 - 2Q^2 +18Q

This can be solved using simple power rule or x n = nxn-1

dD/dQ = 4*6Q4-1 + 2*2Q2-1 + 1*18Q1-1

=24Q3 + 4Q + 18
