An exponential function f(x) = ab^x f (x) = passes through the points (0, 7000) and (2, 1120). what are the values of a and b

Step by step:

Firstly, we should substitute the points where x is equal to 0 so that we can obtain the a value

And because anything to the power of 0 is 1

Now that we have the value for a, we can substitute it into the 2nd equation to find b

Finally, we rearrange to make b the subject

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8
