what is the starting point and rate of change for
a(x) = 210(1.12)x

Starting point is (0, 210).

Rate of change is 0.12 or 12%.

Step-by-step explanation:

Given:

The given function is:

The above function represents an exponential growth function of the form:

Now, we need to convert the given function in the standard form.

So, we write 1.12 as sum of 1 and a number.

So, 1.12 = 1 + 0.12

Therefore, the given function can be rewritten as:

Now, on comparing it with the general form, we conclude:

Therefore, the rate of change is 0.12 or 12 %.

Also, the starting point on the graph will be when 'x' is 0. So, the starting point is (0,210).
