Which properties are present in a table that represents an exponential function in the form y=bx
Bas_tet [7]

Answer:

y-intercept (0,1)

multiplicative rate of change: b

Step-by-step explanation:

If a table represents an exponential function of the form  y=b^x, then the y-value that corresponds to x=0 is 1.

In other words, the y-intercept (0,1) must be present in the table.

Also the ratio of a subsequent y-value to the previous y-value should give a value of b.

In other words the multiplicative rate of change from the table must be equal to b.
