# For the function {eq}f(x) = x^{\frac{\displaystyle 6}{\displaystyle 7}} {/eq}, find {eq}f''(x), \; f''(0),\ f''(1), \ {/eq} and {eq}\ f''(-1) {/eq}.

## Question:

For the function {eq}f(x) = x^{\frac{\displaystyle 6}{\displaystyle 7}} {/eq},

find {eq}f''(x), \; f''(0),\ f''(1), \ {/eq} and {eq}\ f''(-1) {/eq}.

## Second Order Derivative:

The derivative measures the rate of change of a function with respect to a given variable. Different types of functions have different formula for differentiation. If a function {eq}f(x) {/eq} is a differentiable then it will be denoted as {eq}f'(x) {/eq} which is the first derivative. If the function, is differentiable again, then it will be the second derivative {eq}f''(x) {/eq}.
