Without graphing, write an equation of a line that is steeper than y=1/3x. Write the equation in the comment bellow and explain

FrozenT [24]

The gradient of a line depends on how steep it is. The gradient of y=1/3x is 1/3 so you can use any other number that is higher than 1/3 eg y=2

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.

astra-53 [7]

Answer:

$\frac{dy}{dx}=\frac{1}{2(x-4)}$

Step-by-step explanation:

We are given that a function

$y=ln(x-4)^{\frac{1}{2}}$

We have to find the derivative of the function

$y=\frac{1}{2}ln(x-4)$

By using $lna^b=blna$

Differentiate w.r.t x

$\frac{dy}{dx}=\frac{1}{2}\times \frac{1}{x-4}$

By using formula

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

$\frac{dy}{dx}=\frac{1}{2(x-4)}$

Hence, the derivative of function

$\frac{dy}{dx}=\frac{1}{2(x-4)}$
