### Example Question #1 : Find The Second Derivative Of A Function

Find the second derivative of the following function:

**Possible Answers:**

**Correct answer:**

In order to take any order derivative of a polynomial, all we need to know is how to apply the power rule to a simple term with an exponent:

The formula above tells us that to take the derivative of a term with coefficient and exponent , we simply multiply the term by and subtract 1 from in the exponent. With this in mind, we'll take the first derivative of the given function, and then apply the power rule to each term once again to find the second derivative of the given function:

Now if we take the derivative of the first derivative, we'll get the second derivative of our function:

### Example Question #1 : Find The Second Derivative Of A Function

Find the second derivative of the following function:

**Possible Answers:**

**Correct answer:**

To find the second derivative of any function, we find the first derivative, and then just take the derivative again. If we take the first derivative, we apply the power rule and see that the exponent of x for the first term will drop to 0, which means it becomes a 1, leaving us only with the coefficient 127. The second term is just a constant, so its derivative is 0:

Now we can see that our first derivative is just a constant, so when we take the derivative again to find the second derivative we will end up with 0:

### Example Question #9 : Find The Second Derivative Of A Function

Find the second derivative of the following function:

**Possible Answers:**

**Correct answer:**

To find the second derivative of any function, we start by finding the first derivative. Looking at our function, we'll apply the power rule by bringing down each exponent and multiplying it by the coefficient of its term, then we'll subtract 1 from the new exponent:

Notice that the constant at the end drops off because the derivative of a constant is 0. Now we simply take the derivative one more time to find the second derivative:

### Example Question #10 : Find The Second Derivative Of A Function

Find the second derivative of the following function:

**Possible Answers:**

**Correct answer:**

To find the second derivative of any function, we start by finding the first derivative. We do this by applying the power rule to each term, multiplying each term by the value of its exponent and then subtracting 1 from the exponent to give its new value:

Now we simply take the derivative of the first derivative to find the second derivative:
