New houses are being built in a neighborhood. The table shows the exponential change in the number of houses in the neighborhood over the last 6 years. Which exponential function best models the data?

Given the following exponential table, select the correct response from each sentence. The initial value is​ (a)   . The table is an example of a growth or decay?​ (b)   .The equation for the table is ​ ​ (c)   .

• 6

• 0.5

• decay

• growth

Write an exponential function from the table: 

• f(x) = 2(4)^x

• f(x) = 4(2)^x

• f(x) = 4x + 2

• f(x) = 2(4)x

Write the equation of the exponential function for the given table.

• y = -2(1/2)^x

• y = 2(1/2)^x

• y = 2(2)^x

• y = 1/2(2)^x

Write the equation that represents the table below:

• y=½(4)^x

• y=2(4)^x

• y=4(2)^x

• y=4(½)^x

Write the exponential equation that represents the given table.

Write the exponential equation that represents the given table.

Write the equation of the exponential function for the given table.

• y = 2(1/3)^x

• y = -2(1/3)^x

• y = 1/3(2)^x

• y = 2(-1/3)^x
