Which table represents a direct variation function?

A table with 6 columns and 2 rows. The first row, x, has the entries, negative 3, negative 1, 2, 5, 10. The second row, y, has the entries, negative 4.5, negative 3.0, negative 1.5, 0.0, 1.5.

Dwight creates a table of values for a function and plots the points. He finds that one y value divided by the next y value produces the same answer each time. What kind of function did he graph?

linear

quadratic

square root

exponential

A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entries three-fourths, three-halves, 3, 6, 12.

f(x) = 3(2x)

f(x) = 2(2x)

f(x) = 3(3x)

f(x) = 2(3x)

The rate of change between 1 and 2 trees is different than the rate of change between 2 and 3 trees.

The rate of change between 1 and 2 trees is different than the rate of change between 1 and 3 trees.

The rate of change between 2 and 3 trees is different than the rate of change between 3 and 4 trees.

The rate of change between 2 and 3 trees is different than the rate of change between 3 and 5 trees.
