Quiz about Math Scatter

Question 1

Julie made 25 international long-distance phone calls to London last month. The scatterplot shows the length and cost of each phone call she made. Which conclusion is best supported by the scatter plot?

Accepted Answer

There is no relationship between the length of a call and the cost of a call.

Answer

As the length of a call increases, the cost of the call increases.

Answer

As the length of a call increases, the cost of the call remains the same.

Answer

As the length of a call increases, the cost of the call decreases.

Question 10

Which correctly describes the two transformations that were used to create the image on the graph?

Accepted Answer

Reflection over the y-axis and a rotation 90^o counter clockwise

Answer

(x+10, y) and reflection over x-axis

Answer

Rotation 90^o clockwise and a reflection over the x-axis

Answer

Reflection over the x-axis ad a translation (x+6,y)

Question 11

Graph D

Question 13

Which statement below describes the comparison of rate of change between the linear function f(x) and the exponential function g(x).

Accepted Answer

g(x) will eventually exceed the rate of change of f(x).

Answer

g(x) rate of change is ALWAYS greater than f(x) rate of change.

Answer

g(x) is NEVER greater than f(x) rate of change.

Answer

There is not enough information to compare the rate of change of f(x) to g(x).
