i am going to answer question 1, so q1 is a number line
Answer:x^2-y^2
Step-by-step explanation:
(x+y)(x-y) = x^2 -xy +xy -y^2 so it becomes x^2-y^2
Using it's concept, the range of the given exponential function is:
C. 0 < y ≤ 46638.
<h3>What is the range of a function?</h3>
The range of a function is the set that contains all possible output values for the function.
In this problem, the function is:
y = 46,638(0.78)^x.
It is an exponential function with initial value 46,638 and rate of change 0.78. Exponential functions that are not shifted down, such as this one, are never negative nor zero, hence the range also has the restriction y > 0, and is given by:
C. 0 < y ≤ 46638.

Answer:
44
Step-by-step explanation:
If a serving size is 1/2 ounce, there are 2 servings (2/2) per ounce. Let's multiply this by the total ounces.
22 × 2 = 44
There are 44 servings in the bottle of ketchup.
