Given: f(x) = 22(1.77)X Is this exponential growth or decay?

What is the rate of growth or decay?

What was the initial amount?

Growth

Rate of growth is 77%

Initial amount is 22

Step-by-step explanation:

Generally, the exponential equation can be written as;

F(x) = I(1 + r)^n

where I is the initial value, r is the rate is percentage

From the question, we can see that the initial value is 22

Kindly recall that we can write 1.77 as 1+ 0.77

Now 0.77 is same as 77/100 which simply imply77%

Thus, we have 77% as the rate
