Answer:

True. That is a function.

Step-by-step explanation:

A function just means that every input has only one output. The simpler way to do these is the vertical line test. Draw a vertical line anywhere on the graph and see if the vertical line is intersected in two places. If the vertical line is crossed twice, the graph isn't a function.

SOLVE. integration of (1-v) /(1+v^2)

Nutka1998 [239]

$\displaystyle\int\frac{1-v}{1+v^2}\,\mathrm dv=\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv$

The first integral is already standard and has an antiderivative in terms of $\arctan v$ . For the second integral, take $w=1+v^2$ so that $\dfrac{\mathrm dw}2=v\,\mathrm dv$ . Then

$\displaystyle\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv=\arctan v-\frac12\int\frac{\mathrm dw}w$
$=\arctan v-\dfrac12\ln|w|+C$
$=\arctan v-\dfrac12\ln(1+v^2)+C$
