Question

(1) Which is a correct formula for finding the derivative of the product of two functions

Answer 1

The correct formula for finding the derivative of the product of two functions is d/dx(a.b) = a'(x) * b(x) + a(x) * b'(x)

The formula for finding the derivative of the product of two functions

From the question, we have the following parameters that can be used in our computation:

The product of two functions

Let two functions be represented as

a(x) and b(x)

Such that

f(x) = a(x) * b(x)

The product rule states that

if f(x) = a(x) * b(x)

Then

d/dx(a.b) = a'(x) * b(x) + a(x) * b'(x)

Hence, the formula is d/dx(a.b) = a'(x) * b(x) + a(x) * b'(x)

Answer 2

We will write formula for finding the derivative of the product of two functions

`(d)/(dx)(a\cdot b)=a^(\prime)\cdot b+a\cdot b^(\prime)`

So, the answer will be the first option
