What Is Precalculus?

Precalculus is a well-crafted course. It is designed for students who have not yet studied several advanced mathematical concepts.

Indeed, the majority of them lack protection in their standard courses. Thus, despite having studied algebra, geometrical, and other subjects, they still know little about them.

How To Solve Precalculus Answers?

There are several ways of solving the precalculus homework questions. You can choose anyone or multiple options to solve the sums. Following are some of the ways to solve the sums based on Precalculus.

Use Of Precalculus Calculator

Students progress through their educational careers. Also, they attain increasingly advanced levels in various scientific fields and calculus. It is time they need a device in one form or another.

It is never possible to find anything as powerful as the human brain. Yet certain aspects of the students’ study process require rapid and accurate outcomes. Also, no student should ever find it independently.

That is why there is a calculator. With the app we’re discussing today, we hope to take the idea of a calculator to the next level. We are pleased to introduce the free online precalculus calculator. Students can use it for mathematical needs. Also, it will become relatively easy to get the Calculus Answers.

Example Of Pre-Calculus Equations

Question:
Think that 𝑦 = 𝑓(𝑥)
For the above function, the following facts are actual regarding its derivative.

𝑑𝑦/𝑑𝑥 = 𝑓 ′ (𝑥).

𝑓 ′(𝑥) > 0 for 𝑥 < −5 and 0 < 𝑥 < 2

𝑓′(𝑥) < 0 for −5 < 𝑥 < 0 and 𝑥 > 8.

𝑓′(𝑥) = 0 for 2 < 𝑥 < 8.

At the following 5 points, Is the function increasing, decreasing, or constant?

1. ) 𝑥 = −7

2. ) 𝑥 = −3

3. ) 𝑥 = 1

4. ) 𝑥 = 4 5. ) 𝑥 = 10

Answer-

Here, f'(x) is the rate of change of the function f(x). Thus, when f'(x) < 0 the function f(x) is decreasing, when f'(x) = 0, f(x) is constant (flat, if one is looking at a graph), and f'(x) > 0 means f(x) is increasing. It is important to remember these apply to the point x, and the function can change drastically from one x value to another.

1) at x = -7, x < -5 applies and from the given information, f'(x) > 0 for that region; therefore f(x) is increasing when x=-7.

2) at x = -3, -5 < x < 0 applies and f'(x) < 0 in that region; therefore, f(x) is decreasing at x=-3.

3) – 5 is handled similarly.
