If the exponential function passes through the points (3,25) and (8,10), the value of b is 0.833
The given exponential equation is:
The function passes through the points (3, 25) and (8, 10)
Substitute x = 3 and y = 25 into the function
............................(1)
Substitute x = 8 and y = 10 into the function
.............................(2)
Divide equation (2) by equation (1)
Therefore, if the exponential function passes through the points (3,25) and (8,10), the value of b is 0.833
