La función h(x) es uno a uno en su dominio, por lo tanto es invertible. Y la inversa es:

g(x) = [(x + 3)*4 - 5]/(x + 3 - 1)

<h3>¿Es la función h(x) invertible?</h3>

La función esta definida como:

h(x) = -3 + | (5 - x)/(4 - x) |

El dominio es (4, 5] y el rango es [-3, ∞).

Claramente la función es uno a uno en ese intervalo, como podemos ver en el grafico abajo.

Ahora sabemos que la función es invertible en su dominio, entonces debemos encontrar otra funcion g(x) tal que:

h(g(x)) = x

Entonces debemos tener:

-3 + | (5 - g(x))/(4 - g(x)) | = x

| (5 - g(x))/(4 - g(x)) | = x + 3

Podemos remover el valor absoluto:

(5 - g(x))/(4 - g(x)) = x + 3

5 - g(x) = (x + 3)*(4 - g(x))

5 - g(x) + g(x)*(x + 3) = (x + 3)*4

g(x)*(x + 3 - 1) = (x + 3)*4 - 5

g(x) = [(x + 3)*4 - 5]/(x + 3 - 1)

Esa es la función inversa de h(x).

5x+21+178/(x-7)<br> How do I solve for domain and range on this equation?
Luda [366]
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.

For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.

Under A straight line basis which is a method of computing depreciation and amortization by dividing the difference between an asset's cost and its expected salvage value by the number of years it is expected to be used. Also known as straight line depreciation or straight line amortization, this is the simplest depreciation method. But instead of that find The rate of depreciation
100/5 years=20% depreciation rate per year
Total cost 250×50=12,500
Salvage value 40×50=2,000
Subtract the salvage value from the total cost of televisions
12,500−2,000=10,500
In the first year the depreciation is
10,500×0.2=2,100
Book value
12,500−2,100=10,400
In the second year the depreciation is
10,500×0.2=2,100
Book value
10,400−2,100=8,300
In the third year the depreciation is
10500×0.2=2100
Book value
8300-2100=6200

the book value for all of the televisions at the end of the third year is 6200

\frac{ x^{3} }{ x^{2} -4}: \frac{ x^{3} -9 x^{2} }{ x^{2} +7x-18}= \\ = \frac{ x^{3} }{(x+2)(x-2)}* \frac{ x^{2} +7x-18}{ x^{2} (x-9)}= \\ = \frac{ x^{3} }{(x+2)(x-2)}* \frac{(x-2)(x+9)}{ x^{2} (x-9)}= \\ = \frac{x(x+9)}{(x+2)(x-9)}
