Math 124 Exam #1 questions n correct
answers rated A+
average rate of change - correct answer ✔✔ f(b)-f(a)/b-a
AKA: change in y divided by change in x
A= Pb^t - correct answer ✔✔ P= initial value aka Y intercept
b= base (growth or decay)
exponential growth - correct answer ✔✔ base value is greater than 1
exponential decay - correct answer ✔✔ base value is less than 1
A= P(1+r/n)^nt - correct answer ✔✔ compound interest formula
P= initial value
r= rate
n= number of times compounding (quarterly = 4 etc)
t= time
A= Pe^rt - correct answer ✔✔ Compounded continuously formula
P= initial value
e= NOT A VARIABLE!!! (e is a number)
r= rate expressed as a decimal
t= time
