Question:

Find f'(x) given f(x)= 3x^2+cos(x)-7x^5

the exponent 2 is multiplied by the 3 and then 1 is subtracted from the 2 so it would be 6x plus the derivative of cos(x) which is -sin(x) minus 35x^4 the complete answer is 6x-sin(x)-35x^4

First, you distribute the 6 into (2x-3) and multiply it with the 2x and -3 the result of that is 12x-18 then you distribute the -1 into (5x+7) and get -5x-7 after distributing both sides, you combine like terms and get 7x-25
