Given:
Given that the values of x and y in the table.
We need to determine the equation for the exponential function represented in the table and graph the equation.
Equation for the exponential function:
The general equation for the exponential function is given by
------- (1)
Substituting the coordinate (0,6) in equation (1), we get;
Thus, the value of a is 6.
Substituting a = 6 in equation (1), we have;
-------- (2)
Substituting the coordinate (1,12) in equation (2), we get;
Thus, the value of b is 2.
Substituting b = 2 in equation (2), we get;
Thus, the equation for the exponential function is
The image of the graph of the exponential function is attached below:
