If f(x) = 2x and g(x)=1/X what is the domain of (fºg)(x)?

Mathematics

Firlakuza [10]2 years ago

Answer:

(f*g) (x) simply means we obtain the product of f(x) and g(x). We are given that;

f(x)=2x

g(x)= 1/x

(f*g) (x) = f(x) * g(x)

(f*g) (x) = 2x * 1/x = 2

This is a horizontal line defined everywhere on the real line. The domain of  (f*g) (x) is thus ( -∞, ∞)

I need to answer number one I will give as many points as I can for the question and I will mark brainiest
Grace [21]

Answer:

  • diagram is below
  • 6, 11, 16, 21
  • s[n] = s[n-1] +5
  • 26, 31, 36

Step-by-step explanation:

a) See below for the next diagram in sequence.

__

b) The numbers of straws in each diagram are ...

  6, 11, 16, 21, ...

__

c) Each term is 5 more than the previous one, so the recursive rule for the number of straws is ...

  s[1] = 6

  s[n] = s[n-1] +5

__

d) The next three terms of the sequence are ...

  ..., 26, 31, 36, ...

f(x)=4 hallar el dominio, codominio, ceros o raices, vertices, asintotas, tabla de valores, graficas, identificar el tipo de fun
nekit [7.7K]

Answer:

Tipo de función: Función Constante o Función Polinómica de Orden Cero

Dominio: Dom \{f(x)\} = \mathbb{R}

Codominio: Ran \{f(x)\} = 4

Asíntota: y = 4

Raíces: No tiene.

Vértices: No tiene.

La tabla de valores y el gráfico se encuentran adjuntos al fondo.

Step-by-step explanation:

Sea f(x) = 4, el cual representa a una Función Constante o Función Polinómica de Orden Cero, cuyos dominio y codominio son Dom \{f(x)\} = \mathbb{R} y Ran \{f(x)\} = 4. No tiene vértices. Esta función tiene una asíntota horizontal coincidente con la función (y = 4) y carece de raíces al ser f(x) \ne 0 para todo x\in \mathbb{R}.

Finalmente, agregamos una tabla de valores y la gráfica asociada a la función:

x         -2         -1         0         1          2

y         4          4         4         4         4

Lara has three cats: Socks, Princess, and Luna. The ratio of Sock's weight to Princess's weight is 4:5. The ratio of Princess's
romanna [79]
A = Sock's weight
b = Princess' weight
c = Luna's weight

a : b = 4 : 5
b : c = 6 : 7

at this point, we have to change the 2 ratios (a : b and b : c) into one ratio (a : b : c)
to do that, we have to change the ratio number so the number b in both ratio is the same

a : b = 4 : 5 = 24 : 30
b : c = 6 : 7 = 30 : 35
From that we can conclude that
a : b : c = 24 : 30 : 35

Since we're looking for the ratio of Sock's weight to Luna's weight, it will be
a : c = 24 : 35
