Question

Domain and range and function

Choices for domain are

X | X greater than 0 or

X | x greater than or equal to 0 or

All real numbers

Square bracket 0 infinity

Parenthesis negative infinity positive infinity

Range

Y | Y greater than 0 or

Y | Y greater than or equal to 0 or

All real numbers

Square bracket 0 infinity or

Parenthesis 0 infinity or

negative infinity positive infinity

Function 1 to 1 , onto both 1 to 1 and onto

Or neither 1 to 1 nor onto

And discrete , continuous or neither continuous nor discrete

Answer 1

#1

Domain

• The set of x values

Here the arrows are going infinite directions

• (-oo,oo)
• All real numbers

#2

Smae for range

• The set of y values

Arrows approaching infinity

• (-oo,oo)
• All real numbers

#3

It fails in horizontal line test and vertical line test

• One one and onto

Also

• The function is continuous everywhere
