Type in expanded form. Use parentheses to indicate multiplication. (-3x)^4

Serhud [2]

We have $\frac{5}{12}$ of 252 people who have a personalized black disc

Number of people who would have personalized flying disc = $\frac{5}{12}*252= \frac{2*252}{12}=105$ people

Then we work out the number of people who like to play disc golf:
$\frac{25}{175}*105= \frac{25*105}{175}=15$ people

So we have 15 people who like to play disc golf and have personalised black disc.

eduard

Answer:

A) $1$

Step-by-step explanation:

Given:

A graph of a function.

When we analyze the given graph, it is of a parabola.

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) $1$
