Question

COuld someone help me on this question,

Find the derivative:

f(x) = 3x^5-5x^3+4

Answer 1

f'(x) = 15x^4 -15x

Answer 2

sorry, second term is -15x^2

Answer 3

Any chance you could tell me the steps? thanks

Answer 4

f(x)=ax^n
f'(x)=nax^(n-1)
so for
f(x)=3x^5-5x^3+4(x^0)
f'(x)=5(3x^4)-3(5x^2)+0=15x^4-15x^2

Answer 5

thanks
