Answer:

-2n^2+2n+8

Step-by-step explanation:

g=2n+4

f=2n^2-4

g-f = 2n+4 - (2n^2-4) = -2n^2+2n+8

. Find the inverse of the function below on the given interval and write it in the form yequalsf Superscript negative 1 Baseline

Elena L [17]

Answer:

The inverse of the function is $f^{-1}(x)=\frac{x-5}{3}$ .

Step-by-step explanation:

The function provided is:

$f (x)=3x+5$

Let $f(x)=y$ .

Then the value of x is:

$y=3x+5\\\\3x=y-5\\\\x=\frac{y-5}{3}$

For the inverse of the function, $x\rightarrow y$ .

⇒ $f^{-1}(x)=\frac{x-5}{3}$

Compute the value of $f[f^{-1}(x)]$ as follows:

$f[f^{-1}(x)]=f[\frac{x-5}{3}]$

$=3[\frac{x-5}{3}]+5\\\\=x-5+5\\\\=x$

Hence proved that $f[f^{-1}(x)]=x$ .

Compute the value of $f^{-1}[f(x)]$ as follows:

$f^{-1}[f(x)]=f^{-1}[3x+5]$

$=\frac{(3x+5)-5}{3}\\\\=\frac{3x+5-5}{3}\\\\=x$

Hence proved that $f^{-1}[f(x)]=x$ .

What is the slope of the line that passes through the points(-7,-4) and (-11,-4) in simplest form

Alchen [17]

Answer:

Step-by-step explanation:

to find slope, you can use the formula y2 - y1 / x2 - x1

in this case (-4 - (-4)) / (-11 - (-7))

0/-4

slope is 0 which means that the line has a constant x or y (in this case y) so the line ends up looking like --------- instead of _—*
