For each x you have ONE g(x), so it’s one to one
To graph the inverse, draw a line that goes through the origin at 45 degree angle and then draw the mirror image of the graph based on that line. See the image

How do I convert standard form to point slope

Fittoniya [83]

The point-slope form:

$y-y_1=m(x-x_1)$

$(x_1,\ y_1)$ - given point

$m$ - given slope

The standard form:

$Ax+By=C$

$y-y_1=m(x-x_1)$ <em>use distributive property</em>

$y-y_1=mx-mx_1$ <em>add $y_1$ to both sides</em>

$y=mx-mx_1+y_1$ <em>subtract $mx$ from both sides</em>

$-mx+y=-mx_1+y_1$ <em>change the signs</em>

$mx-y=mx_1-y_1$

Evaluate the following integral in cylindrical coordinates triple integral 1/(1+x^2+y^2) dzdxdy z=0..2 y=0..square root(1-x^2) x

sertanlavr [38]

In cylindrical coordinates, we take

$x=r\cos\theta$

$y=r\sin\theta$

$z=z$

so that $\mathrm dx\,\mathrm dy\,\mathrm dz=r\,\mathrm dr\,\mathrm d\theta\,\mathrm dz$ .

We have

$1+x^2+y^2=1+r^2$

and the integral is

$\displaystyle\int_0^2\int_0^\pi\int_0^1\frac r{1+r^2}\,\mathrm dr\,\mathrm d\theta\,\mathrm dz=\frac{\ln2}2\int_0^2\int_0^\pi\mathrm d\theta\,\mathrm dz=\boxed{\pi\ln2}$
