Problem 1
Answers:
Domain:
Range:
--------------------
Explanation:
The domain is the set of allowed x inputs of a function. The smallest x value we can use is x = -3 (note the very left-most point of the graph). The right-most point involves x = 5, but we can't actually use this x value due to the open hole. So that's why we don't have "or equal to" attached to the 5.
The range is the set of possible y outputs. The lowest we can go is y = -4, but we don't include this as part of the range. The largest y can get is y = 3. So the range is
===========================================
Problem 2
Answers:
Domain:
Range:
--------------------
Explanation:
We use the same idea as in problem 1. Both endpoints are open holes, so we don't include them as part of the domain and range. For instance, we can't include x = 4 but we can get closer and closer to it. The same idea applies to the range as well.
===========================================
Problem 3
Answers:
Domain:
Range:
--------------------
Explanation:
The same idea applies as used earlier. This time we include both endpoints, so we have "or equal to" as part of each inequality sign.
Answer:
a) He substituted 0.8 instead of 0.08.
b) $264
Step-by-step explanation:
From the question, the principal is p= $275, the rate is r=0.08, and the time is t=12 years.
We substitute into the formula to get:
a) The mistake is that, he substituted 0.8 instead of 0.08.
b) The correct amount is $264
Hey there!
<h2>ANSWER:All numbers are positive except -1. If a number is negative, then that negative number will be less than a positive. All are positive and -1 is negative. Since that's the only negative, -1 is the smallest number.
Hope this helps!
