In Exercise, find the derivative of the function.<br> y = ln(3 + x2)
erastovalidia [21]

Answer:  \dfrac{2x}{3 + x^2}

Step-by-step explanation:

We know the property of derivative: \dfrac{d}{dx}(\log (x))=\dfrac{1}{x}

Given function : y=\ln(3 + x^2)

Differentiate both sides with respect to x , we get

\dfrac{dy}{dx}=\dfrac{d}{dx}(\ln(3 + x^2))

\Rightarrow\ \dfrac{dy}{dx}=\dfrac{1}{3 + x^2}\cdot\dfrac{d}{dx}(3 + x^2)  [By Chain rule]

\Rightarrow\ \dfrac{dy}{dx}=\dfrac{1}{3 + x^2}\cdot(0+2x)

[Since \dfrac{d}{dx}(a)=0 , where a is scalar and \dfrac{d}{dx}(x^n)=n(x)^{n-1}]

\Rightarrow\ \dfrac{dy}{dx}=\dfrac{2x}{3 + x^2}

Hence, the derivative of the given function is \dfrac{2x}{3 + x^2} .

How many solutions exist for the given equation?<br> 12x + 1 = 3(4x + 1) - 2
VladimirAG [237]

Answer:

Infinite

Step-by-step explanation:

3(4x + 1) - 2

= 12x + 3 - 2 (Multiply the sum in the bracket by 3)

= 12x + 1 (Simplify)

This means that:

12x + 1 = 3(4x + 1) - 2

is the same as

12x + 1 = 12x + 1

Hence, anything that is used to substitute x is correct.
