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)

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
