Question

In the coin value formula, V(t)= P(1+r)^t, which parts form the base of the exponential function? Which parts from the constant, or initial value? Which parts form the exponent?

Answer 1

Answer:

1+r is the base

P is the initial

t is the exponent

Step-by-step explanation:

The base of an exponential function is the factor that contains the variable exponent. Here that would be 1+r.

The initial value is when t=0 or whatever is in front of the exponential part. I'm saying P is your initial but if you aren't convinced with that... Just plug in 0 for t like so:

$V(0)=P(1+r)^0$

$V(0)=P\cdot 1$  *anything to 0 power is 1 (except 0^0)

$V(0)=P$

P is the initial amount.

The exponent is the the variable expression superscript on the repeated factor.  So t is the exponent.

Answer 2

Answer:

Step-by-step explanation:

The base of the exponential function is 1 + r.

The initial value is P.

The exponent is t.
