The single factor tested in an experiment is:
the control
the variable
the data
the hypothesis

The answer is variable.

Step-by-step explanation:

The single factor tested in an experiment is - The variable

Variable is an element or factor that is meant to vary or change in an experiment. Variables are used in Algebra where they are used as a defining variable or 'x' to describe any number.

The variables can be - independent variables, dependent variables, constant variables etc.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
