The straight line is a polynomial. ALL polynomials have real numbers as its domain.
The exponential functions f(x) and g(x) both have the form b^x or b^(-x). Both these exponential functions have a real domain, but the range of both are limited to strictly positive numbers.
Answer:
The answer is B.
Step-by-step explanation:
We already know that there are 60 people in the orchestr, and we know 20 percent play cello. This mean that the second graph will help us figure out how many people play cello.

Step-by-step explanation:
Answer: 4 boxes.
Step-by-step explanation:
We know that each box has 18 ounces of cereal.
We know that:
1 lb = 16 oz
Then:
1 = (1lb/16oz)
Then we can write:
18 oz = 18oz*(1lb/16oz) = (18/16) lb
This means that each box has (18/16) pounds of cereal.
Now, how many boxes we need to buy if we want to have at least 4 pounds of cereal?
If we buy N boxes, we will have N*(18/16) lb boxes of cereal.
Let's find N such that:
N*(18/16) lb = 4lb
N = 4*(16/18) = 3.56
But you can not have a 0.56 of a box, so we should round our number up to the next whole number, then we get:
N = 4.
She should buy 4 boxes.
1. 138
step one - find the cans of soup in boxes
5 times 6 is 30, so there are 30 cans in boxes
step two - find the cans of soup in cases
3 times 36 is 108, so there are 108 cans in cases
step 3 - add them together to find the total number of cans
30+108=138
hope this helps!
