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

natulia [17]

Answer:

$g'(x)=\frac{2e^x-e^{-\frac{x}{2}}}{2(e^x+e^{-\frac{x}{2}})}$

Step-by-step explanation:

We are given that a function

$g(x)=ln(e^x+e^{-\frac{x}{2}})$

We have to find the derivative of function

Differentiate w.r.t x

$g'(x)=\frac{1}{e^x+e^{-\frac{x}{2}}}\times (e^x+e^{-\frac{x}{2}}\times (-\frac{1}{2}))$

By using formula

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

$\frac{d e^x}{dx}=e^x$

$g'(x)=\frac{e^x-\frac{e^{-\frac{x}{2}}}{2}}{e^x+e^{-\frac{x}{2}}}$

Hence, the derivative function

$g'(x)=\frac{2e^x-e^{-\frac{x}{2}}}{2(e^x+e^{-\frac{x}{2}})}$

Can someone give me the answer

Rina8888 [55]

Answer:

A) $y=1.3x+10$

Step-by-step explanation:

1) Plug 2 sets of points into slope formula to find the slope:

$\frac{(16.5-10)}{(5-0)}$

$\frac{6.5}{5}$

2) Write the slope as a decimal:

$m=1.3$

3) Plug the slope and two points into point slope form:

$y-10=1.3(x-0)$

4) Distribute 1.3 to x and 0:

$y-10=1.3x$

5) Add 10 to both sides:

$y=1.3x+10$
