Step-by-step explanation:

f°g=f(g(x))

g(x)=x^2-6x

f(x)=1/x

f(g(x))=\frac{1}{x^2-6x}

if the denominator is zero the number is undefined which makes it not in the domain of the function

set x^2-6x equal to 0

the values for x is 0 or 6

so the only value that is not in the domain of f°g is 0 and 6

Hope that helps :)

What do I need to do and what are the steps
Viktor [21]
So allison spent 3/5 meaning she saved 2/5 because 3/5 + 2/5 = 5/5

change the 2/5 into decimals by 2 ÷ 5 = 0.4

multiply $55 with 0.4
55 x 0.4 = 22

A window in the shape of a rectangle as shown below has a width of x+5 and a length of x^2- 3x+7 express the area of the rectang
Ksju [112]

Answer:

x^3+x^2-5x+28

Step-by-step explanation:

since a=lw, the area is (x^2-3x+7)(x+4)

1. distribute parentheses \left(x^2-3x+7\right)\left(x+4\right)=x^2x+x^2\cdot \:4+\left(-3x\right)x+\left(-3x\right)\cdot \:4+7x+7\cdot \:4

2. apply +(-a)=-a rule x^2x+4x^2-3xx-3\cdot \:4x+7x+7\cdot \:4

3. Simplify

    Steps to simplify:

x^2x=x^3

3xx=3x^2

3\cdot \:4x=12x

7\cdot \:4=28

x^3+4x^2-3x^2-12x+7x+28

4. Add like terms =x^3+4x^2-3x^2-5x+28

5. Add like terms =x^3+x^2-5x+28
