The value of the function at x = -1 is 5

<h3>What is function?</h3>

Function can be defined as an expression, rule, or law that defines a relationship between one variable known as the independent variable and another called the dependent variable.

From the information given, we have that;

f (x) = 3 (2)x with x=-1

Now, let's substitute the value of x as - 1 in the function given;

f (x) = 3 (2)x

f (x) = 3 (2) -1

Expand the bracket;

f (x) = 6 - 1

f(x) = 5

Thus, the value of the function at x = -1 is 5

Kayla and Jody are working at a station. They have been given four cards with four different functions on them.

If x=0, then f(x)=-1. The value of -1 makes Function D less than any of the other functions.
f(0)=2(0^2)-1
=2(0)-1
=0-1
=-1

Suppose you are doing a binary search of the list [15, 18, 2, 19, 18, 0, 8, 14, 19, 14]. How many comparisons would you need to

Illusion [34]

Answer:

Three Times.

Step-by-step explanation:

First and foremost a binary search requires that the array be sorted in ascending or descending order.

After the initial step the search goes to the middle most value

i.e. $[0, 2,8,14,14,15,18,18,19,19]$

will be the second 14, which is the first iteration.

Since 14 is less than 19 the search will eliminate the lower half of the including 14, and will iterate again through the array:

$[15,18,18,19,19]$

The array will go to the middle most value which is 18, second iteration. Since 18 is less than 19, the program will eliminate the lower half and be left with two values i.e. $[19,19]$ .

The search will run once i.e. third iteration, and will return key value found.

Grissom draws different sized spheres in a notebook. He knows there is a relationship between the volume of the sphere and the l

grigory [225]

Answer:

The independent quantity in the situation is the length of the diameter.

Step-by-step explanation:

Consider a relationship between two variables.

Of the two variables one variable is dependent upon the other.

Dependent variables are those variables that are under study, i.e. they are being observed for any changes when the other variable values are changed.

Independent variables are the variables that are being altered to see a proportionate change in the dependent variable.

In this case, it is provided that Grissom knows there is a relationship between the volume of the sphere and the length of its diameter.

With every sphere that Grissom draws, the volume of the sphere changes according to its diameter length.

That is the volume of the sphere depends upon the length of its diameter.

Thus, the independent quantity in the situation is the length of the diameter.
