Can someone help me find domain and range? I'll give brainliest if done before 10 mins

a. D= R=

b. D= x = ∞ R=

Step-by-step explanation:

A. The line of the graph has a closed end. Therefore, there is a maximum or minimum value. In this case, it is a maximum. Domain has to do with the x values. The highest value is 6, and the line continues off of the graph to the left. This means that we can assume the values continue on for infinity. This is why you say all x values are equal to or less than 6. The range has to do with the y values. The maximum y value in this graph is 6. Since the line continues on endlessly (to out knowledge), all y values are equal to or less than 6.

B. This graph has two infinite ends on both the left and right. Therefore, we can not determine a maximum or minimum x value for this graph. This is why the x values are infinite. The range is different. From what we can see, the pattern in the graph is constant. We can assume the pattern continues infinitely. The highest y value is 3, and the lowest is -3. This means that all of the y values are equal to or greater than -3, and are also equal to or less than 3.

I hope this makes sense :)

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
