Exponential Expressions
What is the definition of an exponential expression?
Exponential Expression is a way of showing that how many times the base number is multiplied by itself
What is a logarithm
They are a number that represents the power to which the number must be raised to produce a given value
Give a real-life example of an exponential function
If you have a car that costs 10,000 and each year it´s value reduces by 2%. What would be the value after a decade?
What is a geometric sequence
Geometric sequences are sequences in which the next term is found by multiplying the term before by the common ratio.
How would you evaluate an exponential expression
By finding the value of an exponent by multiplying the number, the number of times that the exponent says.
For example
3^4 is 3*3*3*3
How do you evaluate logarithmic expressions
To solve, you have to have to write both sides of the given expression as powers of the same number.
What is an exponential equation and how would you solve it
It is when the variables are the exponents. When solving these equation, you have the same base and will have to use the property of equality in order to get the answer.
What is a growth function
A function were the quantity increases by a common rate
What is the exponential property
The exponential property tells us how many times the base will be multiplied by itself. It is also known as the numerical value of the exponent.
What is Log (x) and Ln (x)
Log(x) is the common log of a logarithm that has a base 10. LN(x) is called the natural log that has base E
How does the graph of an exponential equation work
If an exponent gets bigger, the line gets steeper and will increase exponentially, however, if the exponent decreases the line will get more flat.
What is a decay function
A function were the quantity decreases by a common rate.
How do you write a logarithm as an exponential expression
When you write a logarithm as an exponential expression, the base of the logarithm stays the same, and you have to elevate the base to the exponent of the answer.
