Solve for r to two decimal places. 6 = e4r (Do not round until the final answer. Then round to the nearest hundredth as needed.) Differentiate the following function. f(x)=5-5x+4ex f'(x) = Find f'(x). f(x)=5ex+2x-3 Inx f'(x) = Find the equation of the line tangent to the graph of f at the indicated value of x. f(x)=5 Inx; x=1 y = Find f'(x). f(x)=(8x+6)(5x-3) f'(x)= |
