Writing and Identifying Exponential Functions

The equation for this exponential function is

• y = 1(2^x)

• y = 1(4^x)

• y = 3x

• y = 1(3^x)

The equation for this table is 

• y = 1(2^x)
• y = 1(12^x)
• y = 12x
• y = 12x + 1

The equation for this table is 

• y = 100(2^x)
• y = 2^x
• y = 2x + 100
• y = 100^x

The equation for this table is

• y = 3x + 50
• y = 50^x
• y = 3^x
• y = 50(3^x)
