Step-by-step explanation:

Given:

A graph of a function.

When we analyze the given graph, it is of a <em>parabola</em>.

To find:

The interval of values of x where the function is increasing.

Solution:

First of all, let us learn about the meaning of increasing and decreasing functions.

1. A function y=f(x) is known as increasing  in an interval a when

Value of y keeps on increasing when we move from the value of x from a to b.

2. A function y=f(x) is known as decreasing  in an interval a when

Value of y keeps on decreasing when we move from the value of x from a to b.

On analyzing the given graph , we can see that the graph is decreasing on the interval: -\infty

and is increasing on the interval: 1

When we choose from the options,

The correct answer is option A) 1

Lelu [443]

Answer:

15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Step-by-step explanation:

Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo​ se deben realizar los siguientes cálculos:

30/200 = 15/100 = 15%

45/200 = 22.5/100 = 22.5%

55/200 = 27.5/100 = 27.5%

38/200 = 19/100 = 19%

32/200 = 16/100 = 16%

Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.
