Find the second derivative of the function.

Step-by-step explanation:

we would like to figure out the second derivative of the following:

we can rewrite it thus rewrite:

take derivative in both sides:

by sum derivation we obtain:

by exponent derivation we acquire:

take derivative In both sides once again:

use difference rule which yields:

use exponent derivation which yields:

by law of exponent we get:

hence, our answer is d)

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
