How to solve piecewise functions step by step?

1 answer:

5 0

If you can graph a function, you can graph piecewise functions. Each one of them is a different line or curve within the domain for that specific line of curve. If the domain states it's less than or greater than a number, you circle that point on the line. If the domain states it's also possibly equal to the point at the beginning or the end, you make a closed dot.

I"m sure that's clear as mud, please respond with any additional questions.

A man is 13 times as old as his son is. In 10 years he will be 3 times as old as his son is now. How old are they now?

valkas [14]

Answer:

the son is 2

man is 26

+10 yrs

son=12

man=36

Step-by-step explanation:

Let the son's age be x.

Then the father's age is 13x.

In ten years their ages will be (x+10) and (13x+10).

(13x+10)=3(x+10)

13x+10=3x+30

10x=20

x=2

The son is 2 years old.

Here are two steps from the derivation of the quadratic formula.

Lana71 [14]

What took place between the first step and the second step? - A. Taking the square root of both sides.

As we can see from the first to second step, the left side of the equation goes from being squared to not being squared. While on the right side of the equation, the square root is now being taken.

Hope this helps!! :)
