Answer:
A
Step-by-step explanation:
The function is a quadratic whose graph is a parabola. All parabolas have no limitations on their domain. This means the domain of the function is all real numbers.
This parabola has a minimum value since its leading coefficient is positive. Its vertex is at (0,-2). This means its range is all values greater than -2 or y ≥ -2.
An inverse of a function is its reflection across the y=x line. This results in (x,y) in the function becoming (y,x) in its inverse. The domain of the function becomes the range of the inverse and the range of the function becomes the domain of the inverse. Inverse has x ≥ -2 as its domain and all real numbers for its range.
Answer:
24
Step-by-step explanation:
If this is an answer 24 because when there were 50 tickets sold there were 12 so when there is 100 tickets sold you double 12 to get 24
Hope this makes since and please do not come after me if this is wrong.

Step-by-step explanation:
Both figures are cuboids whose volume (V) is calculated as
V = lbh ( l is the length, b is the width and h the height )
(8)
V = 6 × 6 × 10 = 36 × 10 = 360 ft³
(9)
V = 11 × 14 × 4 = 616 in³
Answer: CONFOUNDING VARIABLES
Step-by-step explanation: Confounding variables are
unexpected external factor that affects both variables of interest, confounding variables usually gives the false impression that changes in one variable leads to changes in the other variable, when, in Actual, it is the external factor that caused the change being investigated. Confounding variables usually leads to wrong conclusions during research and experiments and are capable of causing biased outcomes when the real cause and effect relationship is not determined.
