The Identity function i behaves just like the number 1. That is (F o i)=f and (i o g)= g

andrezito [222]

I'll denote the identity function by $\mathrm{Id}$ . Then for any functions $f$ with inverse $f^{-1}$ ,

$\begin{cases}f\circ\mathrm{Id}=f\\\mathrm{Id}\circ f=f\\f\circ f^{-1}=\mathrm{Id}\end{cases}$

One important fact is that composition is associative, meaning for functions $f,g,h$ , we have

$(f\circ g)\circ h=f\circ(g\circ h)$

So given

$h=f\circ g$

we can compose the functions on either side with $g^{-1}$ :

$h\circ g^{-1}=(f\circ g)\circ g^{-1}=f\circ(g\circ g^{-1})$

then apply the rules listed above:

$h\circ g^{-1}=f\circ\mathrm{Id}=f$

Given f(x)= 17 – x^2, what is the average rate of change in f(x) over the interval [1, 5]?

Setler79 [48]

Answer:

-6

Step-by-step explanation:

Average rate of change = $\frac{f(b)-f(a)}{b-a}$ = $\frac{(17-5^{2)}-(17-1^{2}) }{5-1}$ = -6

Answer:

C. 846 in.^2

Step-by-step explanation:

Look at the net.

There is one rectangle that is (21 + 3 + 21 + 3) inches long. Its length is 48 inches long. Its width is 15 inches.

There there are two small rectangles. Both are 3 inches wide and 21 inches long. The total length is (21 + 21) inches = 42 inches

total area = 48 in. * 15 in. + 42 in. * 3 in.

total area = 720 in.^2 + 126 in. * 3 in.

total area = 846 in.^2
