      The function must first be revised before a derivative can be taken. Begin with . y = (3x2+5)1/x . Apply the natural logarithm to both sides of this equation getting . Differentiate both sides of this equation. The left-hand side requires the chain rule since y represents a function of x . Use the quotient rule and the chain rule on the right ...

      Only the first equation is linear in y and x. The second equation contains an x-squared term. This equation is a quadratic equation. The third equation is also is not a linear equation in x and y; here the natural logarithm of x is in the equation. This equation is commonly known as a semi-log equation.

      If x = 1, then f (1) = 1 and the slope of the line tangent to this graph at x = 1 is 3. You evaluate the derivative at the x value to get this number, and it will change as x changes. In the “Big Picture”: For an itsy bitsy step off of 1 to the right, the y value will go up 3 times the size of that step.
