One

Randomization not only occurs, but the person conducting the experiment has no idea who is receiving what. If there are two groups, there are members in each group that receive a drug and others who do not.

Two

poses no interference on the subjects. The information is obtained. It is pretty objective. When the survey is complete so is the person interviewed by those conducting the survey.

Treatment is imposed at least on 1/2 the participants.

Please help!! Which values of a and b in the exponential function y=a*b^x would result in the following graph?

Masja [62]

Answer: $a=-3, b=2$

Step-by-step explanation:

1. To solve this problem substitute the values of $a$ and $b$ into the function $y=a*b^{x}$ and prove for the value $x=0$ .

2. When $x=0$ , $b^{0}=1$ and $a*1=a$ ; this means that the graph of the function should cut in the axis $y=a$ , if this does not happen, the values of $a$ and $b$ are not the right ones.
