What is an Asymptote?
A line that a curve approaches but never crosses.
What equation is Asymptote?
y=0
What is an Initial Value/I.V. ?
The starting value in an exponential function
What is the common/constant ratio represented in f(x)=a.b^x?
b
What equation do you use for exponential growth?
a.b^x where b > 1
Is the Initial Value x or y intercept?
y-intercept
What is the base for exponential Decay?
0 < b < 1.
What is the equation for linear problems?
y=mx+b
What equations is for exponential problems?
a.b^x
Is the equation y=3x-2 linear or exponential?
Linear
Is the equation y=2^x linear or exponential?
Exponential
What is Linear?
Adds or subtracts the same amount every time and on a graph is a straight line.
What exponential?
Multiplies and divides the same amount every time. On a graph it curves up or down depending on if it is growing or decaying.
The y-intercept on a T-chart is what?
The 0 value.
What is the domain in exponential functions?
All real numbers.
What is the range for all exponential functions?
y > 0.
What is the domain for all Linear functions?
All real numbers.
What is the range for all Linear functions?
All real numbers.
What equation is for compounds?
A=p(1+ r/n)^nt.
In A=p(1+r/n)^nt what is P?
Principal/”Initial number”.
What is r A=p(1+r/n)^nt
Rate/percent/decimal.
What is n in A=p(1+r/n)^nt ?
Number of times compounded per year (Annual, daily, yearly etc).
What is t in A=p(1+r/n)^nt ?
Time in years (for example 10 years would go in t)
