Wasnt sure if you were asking just for the standard form of that equation
<span>(15y − 9 + 6y^2) + (10 − 5y) = 0 ) or if you wanted the equation simplified and then in standard form ( 6y^2 + 10y + 1 = 6 ) so i did both </span>

Given the function f\left(x\right)=-3x+6f(x)=−3x+6 with a domain of [-2, 7), identify the range of the function using same notat

Aliun [14]

Answer:

The range of the function is represented by $Ran\{f(x)\} = (-15, 12]$ .

Step-by-step explanation:

Let be $f(x) = -3\cdot x + 6$ , for $x \in [-2,7)$ . As we notice that $f(x)$ is an inyective function, that is, the inexistence of two or more domain element with the same image, with a monotone behavior, we can obtain the bounds of the range of the function by evaluating the expression:

Lower bound ( $x = -2$ )

$f(-2) = -3\cdot (-2)+6$

$f(-2) = 12$

Upper bound ( $x = 7$ )

$f(7) = -3\cdot (7)+6$

$f(7) = -15$

The range of the function is represented by $Ran\{f(x)\} = (-15, 12]$

The list shows numbers in order from least to greatest. Negative 34, negative 2 and three-fourths, blank, negative 1.5, 0, 2.3,

blsea [12.9K]

Options

-2.5
-2
$-1\dfrac{9}{10}$
-1

Answer:

(B) -2

Step-by-step explanation:

Given the list

$-34.-2\dfrac{3}{4} ,x, -1.5,0,2.3,10,25\dfrac15$

This list has been arranged in order from the least to the greatest.

We are required to find an Integer that can be inserted on the blank line (I have used x) in the list.

An integer is defined as a positive or negative whole number.

Out of the given options, only -1 and -2 are integers. However:

-1 is greater than -1.5

Therefore, it cannot be our result.

The correct answer is -2.
