Question 1
Which type of study best describes the following research most likely to be done?
A researcher is testing out a brand new type of safety suit for fires and is trying to test the maximum threshold of the suit.
Simulation Study
Question 2
Which type of study best describes the following research most likely to be done?
A test is being conducted on a new medicine that is supposed to heal cuts faster. One group is given the actual medicine in a gel type of ointment to apply to the cuts. The second group is given just regular Vaseline that looks like the medicine but has not benefit to put on the cut. The results are then compared.
Experimental Study

To decompose a fraction to one whole, there are different methods to use. The fraction can be decomposed either by division, multiplication(if there are more than one fraction), or addition(if there are more than one fractions).
Example:
Given 8/2, decompose by division:
To do this, divide the numerator by denominator
Answer:Quadratic
Step-by-step explanation:
As the domain values negative infinity, the range values approach infinity.
Domain: If then X=- Infinity
Range:Y= infinity
We need to settle on correct option which follows given domain and range.
Only quadratic function will follow the rule because it's even degree polynomial.
Quadratic function:f(X)= aX^2+bX+c
Degree = 2 and leading coefficient is positive.
Domain:X(-infinity, infinity)
Range: Y(b, Infinity)
