Find the derivative of the function f(x)=-3(2-9x)^(1/4)
I have:
f'(x)=-3[1/4(2-9x)(-9)]+0(2-9x)^(1/4)
=-3[-9/4(2-9x)]
=-3(81/4x-9/2)
=-243/4x+27/2
Did I do that right?
When you took the 1/4 power down front, what should have been left behind as the power on the parenthetical?Find the derivative of the function f(x)=-3(2-9x)^(1/4)
I have:
f'(x)=-3[1/4(2-9x)(-9)]+0(2-9x)^(1/4)
