Differentiate Functions of Other Bases In Exercise, find the derivative of the function.
Maslowich

Answer:

\frac{dy}{dx}=3x^{3x}(lnx+1)

Step-by-step explanation:

We are given that a function

y=x^{3x}+1

We have to find the derivative of the function

Let u=x^{3x}

y=u+1

Taking ln on both sides

lnu=3xln x

By using lna^b=blna

Differentiate w.r.t x

\frac{1}{u}\frac{du}{dx}=3(lnx+x\times \frac{1}{x})=3(lnx+1)

\frac{d(lnx)}{dx}=\frac{1}{x}

\frac{d(u\cdot v)}{dx}=u'v+v'u

\frac{du}{dx}=3u(lnx+1)=3x^{3x}(lnx+1)

Differentiate  y w.r.t x

\frac{dy}{dx}=\frac{du}{dx}

Using the value of du/dx

\frac{dy}{dx}=3x^{3x}(lnx+1)

Write an inequality for the graph.
gregori [183]
First of all, the shaded part is under the line, so it is a smaller than, so we can eliminate D
next, look at the vertex, it is at (5,5), which means when x=5, whatever is inside the absolute symbol has a value of zero, and y will be 5
so the answer is A
