For each coefficient choose whether it is positive or negative.Choose the coefficient with the least value.Choose the coefficient closest to zero.

For Each Coefficient Choose Whether It Is Positive Or NegativeChoose The Coefficient With The Least ValueChoose The Coefficient Closest To Zero class=

Sagot :

From the given graph

a)

If the coefficient is positive, then the graph is upward

If the coefficient is negative, then the graph is downward

In the first 2 figures, the graphs are upward, then

A and B are positive

In the last 2 figures, the graphs are downward, then

C and D are negative

b)

The least coefficient is the coefficient of the graph which nearest to the x-axis

Since graph C is the nearest graph to the x-axis, but we have negative values, then

The least coefficient is the coefficient of the downward graph and farthest from the x-axis, then

D is the least coefficient

c)

The closest coefficient to zero is the graph C
