Question

please answer

A) Domain:all real numbers Range:all real numbers

B) Domain: all real numbers greater than or equal to 0

Range:alll real numbers greater than or equal to 0

C) Domain: all readl numbers greater than or equal to 2

Range: all real numbers greater than or equal to 0

D) Domain:all real numbers Range:all real numbers greater than or equal to 1

Answer 1

The word problem above looks like: y=2x+1. Domain refers to the possible 'x' values and Range refers what 'y' values you will get as an output from the equation. 'x' can be any value on the number line, positive or negative so the Domain would be (-∞,∞). When examining the Range, looking at multiples of ten, positive and negative, help illuminate what the equation will look like. As 'x' goes further negative, so does 'y.' As 'x' goes further positive, 'y' follows suit. This shows that there is no value that neither 'x' nor 'y' cannot be. In other words, 'x' can be any number and so can 'y'. Therefore, the answer to this question is A: Domain: all real numbers Range: all real numbers.
