effect of changing b on graph of f(x)=ax^2+bx+c Solution When the value of b in the quadratic function y = ax^2 + bx + c is changed, the graph\'s shape remains the same, only its position changes. The graph opens upwards or downwards depending on the sign of a. The sign of b has no effect on that. The concavity of the graph is also not affected by the value of b. There is just a shift in the position of the graph which may be upwards, downwards, to the left or to the right. The new graph is located such that the roots of the equation are located at the appropriate location on the x-axis. You can use the link provided below to enter functions with different values of b and see the changes due to it. A change in b only results in a movement of the graph with respect to the x and y axes..

1. Effect of Confederates on Compliance
A study was conducted to see whether participants would ignore a sign that said, "Elevator may
stick between floors. Use the stairs." The study was done at a university dorm on the ground
floor of a three-level building. Those who used the stairs were said to be compliant, and those
who used the elevator were said to be noncompliant. There were three possible situations, two of
which involved confederates. A confederate is a person who is secretly working with the
experimenter. In the first situation, there was a compliant confederate, and in third situation,
there was a noncompliant confederate. The subjects tended to imitate the confederates. What
more do you need to know about the study to determine whether the presence or absence of a
confedertae causes a change in the compliance of subjects?
