Answer:

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

Step-by-step explanation:

In 2x/(x^2 - 1)1/2

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

Apply the property of natural log

ln x^m = m ln(x) move the exponent before ln

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

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

ln(m/n)= ln m - ln n

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

multiply 1/2 inside the terms

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

If f(x) is a linear function, f(- 3) = - 3 , and f(5) = 4 , find an equation for f(x)

uysha [10]

$f(x)=mx+b$

$f(-3)=-3$ meaning that (-3,-3)

$f(5)=4$ meaning that (5,4)

(1 ) Find slope.

$m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{4+3}{5+3}\\m=\frac{7}{8}$

The slope is 7/8

(2) Substitute any ordered pairs in the equation.

I'll use (5,4)

$f(x) = \frac{7}{8}x+b\\4=\frac{7}{8}(5)+b\\4=\frac{35}{8}+b\\32=35+8b\\32-35=8b\\-3=8b\\-\frac{3}{8}=b\\b=-\frac{3}{8}$

Therefore the equation for f(x) is $f(x)=\frac{7}{8}x-\frac{3}{8}$
