Chose the definition for the function

Mathematics
1 answer:
Paul [167]1 year ago

By using studying graph of function, the correct option is the fourth option

What is a function

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here,

For x \geq 1, (Solid dot is given, so equality is maintained here),

At x = 1, y = -1.

This happens for the function y = -2x + 1

So for x \geq 1, the function is y = -2x + 1

Now for x < 1, (Hollow dot is given, so the equality will not be maintained here ),

At x = 1, y = 1

This happens for y = -x + 2

So for x < 1, the function is y = -x + 2

So the function is

y = -2x + 1, x \geq 1,

y = -x + 2, x < 1

Fourth option is correct
