1 would be D.
2. Is A since 3^2=9 and -3^2=9 And 9-9=0. Im pretty sure A. For number 3. Just because the two x-values are 3 and -3. I’m sorry if I’m wrong on #3.

Which is true about the domain and range of a function in the form f(x) = m√x, where m is a real number greater
sveticcg [70]

There is an infinite number of values that are in both the domain and range.

<h3>Define domain and range.</h3>

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values. The collection of all potential inputs for a function is its domain.

Given Data

Range of a function in the form f(x) = m√x, where m is a real number greater than 0

There is an infinite number of values that are in both the domain and range.

The range of a function always has an unlimited number of values when the domain of the function does. The claim is untrue because more than one input and output might have been matched.

Does anyone know how to answer this question? Please write your working calculation as well if you do know the answer. Thanks so
krek1111 [17]

Answer:

Mark as brainliest if helped Thanks!

Step-by-step explanation:

funtion is:

y = \frac{x^2 -1}{2x + 1}

therefore \\\frac{dy}{dx}\\ is

\frac{d\frac{x^2 -1}{2x + 1}}{dx}

\frac{\frac{x^2 -1}{2x + 1}}{x}

\frac{x^2 -1}{(2x+1) x}

Now

\int\limits^2_0 {\frac{x^2 +x +1 }{4x^2 +4 + 1} } \, dx

(Calculation of this it too long and it is hard to type on brainly)

here is the answer though....

= 4/5

=0.8

(c) Emma changed her statement to say that when you multiply two negative decimals and a positive decimal, the product will be p
Kryger [21]
The statement is always true.

Let's take -.12*-.5*.2

-.12*-.5*.2=.012

And:
-.2*-.4*.3=.024

A positive multiplied by a positive is, obviously, a positive.

The result of two negative numbers multiplying together is always positive.

So, negative*negative*positive is a positive answer.

Determine the intercepts of the line. -7x - 6y = -15
Cerrena [4.2K]

Answer:

(0,5/2) y intercept

(15/7,0) x intercept

Step-by-step explanation:

To find the y intercept, let x = 0 and solve for y

0 - 6y = -15

Divide each side by -6

y = -15/-6

y = 5/2

(0,5/2)

To find the x intercept, let y = 0 and solve for x

-7x - 0 = -15

Divide each side by -7

-7x/-7 = -15/-7

x = 15/7

(15/7,0)
