Find the derivative: h(x)=7x/sqrt(5-2x)

Using the chain rule...I figured out my previous post.

  • Calculus - ,

    h(x) = 7x *(5-2x)^-1/2
    dh/dx = 7 (5-2x)^-1/2
    + (7x)d/dx(5-2x)^-1/2

    Use the chain rule on the second term

    d/dx(5-2x)^-1/2 = (-1/2)(-2)(5-2x)^-3/2
    = (5-2x)^-3/2
