Erify that f has an inverse. then use the function f and the given real number a to find (f −1)'(a). (hint: see example 1. if an
zhannawk [14.2K]

The function

... f(x) = (x+2)/(x-1) = 1 + 3/(x-1)

is symmetrical about the line y=x, hence is its own inverse.


We can evaluate the desired derivative directly.

... f'(x) -3/(x-1)²

so f'(2) is

... f'(2) = -3/(2-1)²


(f^{-1})(2)=-3

Resuelve las siguientes ecuaciones y luego verifica<br> A-)3x +1=7<br> B-)2a-2=1+3a
jarptica [38.1K]

Answer:

A) x=2

B) a=-3

Step-by-step explanation:

La primera ecuación dada es,

A) 3x + 1 = 7

Reste 1 de ambos lados, tenemos

3x +1-1=7-1

\Rightarrow 3x=6

Dividir por 3 (ya que 3 es un número distinto de cero) de ambos lados, tenemos

\frac{3x}{3}=\frac {6}{3}

\Rightarrow x=2

Ahora, compruebe si x = 2 es la solución correcta o no.

El lado izquierdo de la ecuación dada es 3x + 1.

Ponga x = 2, tenemos

3\times2+1=7

Que es igual al lado derecho de la ecuación dada.

Por tanto, x = 2 es la solución correcta.

La segunda ecuación es

B) 2a-2=1+3a

Reste 3a de ambos lados, tenemos

2a-2-3a=1+3a-3a

\Rightarrow -a-2=1

Suma 2 de ambos lados, tenemos

-a-2+2=1+2

\Rightarrow -a=3

Multiplica por -1 (como -1 es un número distinto de cero) de ambos lados, tenemos

-a\times (-1)=3\times(-1)

\Rightarrow a=-3

Ahora, verifique si a = -3 es la solución correcta o no

El lado izquierdo de la ecuación dada es 2a-2.

Ponga a = -3, tenemos

2\times(-3)-2=-8

El lado derecho de la ecuación dada es 1 + 3a.

Ponga a = -3, tenemos

1+3\times(-3)=-8.

Aquí, al poner a = -3, el valor del lado izquierdo es igual al valor del lado derecho.

Por tanto, a = -3 es la solución correcta.

One number is three times another number. If the sum of the numbers is 36, determine the two
Svetllana [295]

Answer: biggest no.=27. Smallest number=9

Step-by-step explanation:

Let's take the smallest number as x and the biggest number as 3x since it is 3 times bigger than x.

The sum of these two numbers is 36

3x+x=36

4x=36

X( smallest number)=36/4: 9

While, the biggest number is 3x: 3×9=27
