What are the domain and range of the function x^2-2x^2-4?

Mathematics
1 answer:
jonny [76]3 years ago
7 0

{x}^{2}  - 2 {x}^{2}  - 4 \\  -  {x}^{2}  - 4

The Quadratic Function has the domain as the set of all real numbers.

For the range, start from minimum value to maximum value.

But because the parabola is downward as a < 0. Thus, there are no minimum value but the maximum value instead.

Therefore the range is y <= -4

Which of the following statements is true?
MakcuM [25]

Answer:

e. All of these statements are true.

Step-by-step explanation:

The first statement is true because an experiment is actually the process by which an observation is made. Consider rolling a die. It is called an experiment because we observe which side of the die lands facing upwards and that number is noted.

The second statement is also true because a simple event is the one which can not be further decomposed into an event. (Compound events can be decomposed into simple events).

The third statement is also true that an event is the collection of one or more simple events. An event can contain either simple events of compound events which are basically a combination of two or more simple events.

Hence, we can say that <u>all the statements are true</u>.

What is the equation of the line x–3y=18in slope-intercept form?
Alekssandra [29.7K]

Answer:

y=\frac{1}{3} x-6

Step-by-step explanation:

Write down the slope-intercept form:

y=mx+b

Where m is the slope and b is the y-intercept.

To turn the equation into slope-intercept form, isolate y on the left-hand side:

x-3y=18\\-3y=18-x\\y=-6+\frac{x}{3} \\

Rearrange the equation a bit:

y=\frac{1}{3} x-6
