Answer:
Controlled Experiment
Step-by-step explanation:
The controlled experiment involves the experiment in which all factors are considered as constants whereas one factor is not fixed and that one is independent variable whose effect is to be tested. In short, in controlled experiment one group of data contains control group and one or more other groups are examined by considering all other factors constant except for one factor. The control group is the group that doesn't receive any treatment whereas treatment is applied to experimental group and then effect of treatment is measured through comparing both groups.
Here group of boys is divided in to two groups
The group watched violent cartoon= Experimental group
The group watched cartoons without violence= Control group
The researchers want to know whether the violent actions of boys are linked to violent cartoon and for this purpose these boys are divided into experimental group and control group and after 1 hour of cartoons watching the researcher will observed boys for next two hours.
Hence the study is Controlled experiment.
Answer:
The correct choice is C
Step-by-step explanation:
The given function is:

The degree of this function is odd so the function will rise at one end and fall on the other end.
Since the coefficient of the leading term is negative, the graph of the function will rise at the left and fall on the right.
The correct answer is option C.
X= -1 beacuse negative one plus one is 0 and that will equal zero for both sides
