HELP ASAP PLEASE!!!

Answer 1

Answer:

Option C is correct.

Step-by-step explanation:

An exponential function is of the form:  $y =a(b)^x$ ....[1] where a is the initial value, x is any real number and b is the growth factor  

Also, the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).

Then, the growth "rate" (r) is determined as b = 1 + r.

and the decay "rate" (r) is determined as b = 1 - r

• If b> 1, then it is exponential growth function.

• if 0<b< 1. then it is exponential decay function.

Also, b = 1+ 4

Given the equation:  $y = 50(1.15)^x$

On comparing given equation  with [1] we get;

a = 50 and b = 1.15

Since, b = 1.15 > 1

Therefore, the given equation represents the exponential growth.

(A)

Yes, this $y = 50(1.15)^x$ equation represents the exponential growth.

(B)

Initial value (a) = 50

(C)

Here growth factor, b = 1.15

and

1+ r = 1.15.

⇒$r = 0.15\%$
