Functions
f(x) is called _______ notation.
What is Function?
It's the biggest exponent in a quadratic function.
What is 2?
This number is not in the following function's domain: 1/(x-5)
What is 5?
You cannot take the square root of this kind of number.
What is negative?
3^x is an example of this type of function.
What is an exponential function?
A function outputs this many answers for each input.
What is One?
You can use this method to solve this quadratic equation: x^2 + 3x +2 = 0
What is Factoring?
A rational function has one of these--causing a break in its graph--at a point where its denominator equals zero.
What is a discontinuity?
The following function's domain starts at this number: sqrt(x-7)
What is 7?
This expression is equal to x^5 times x^2?
What is x^7?
This is the name of the set of all x-values you are allowed to plug into a given function.
What is Domain?
You can use this formula to solve this quadratic equation: 3x^2 + 7x + 2 =0
What is the Quadratic Formula?
1/(x-8) has this type of discontinuity at x = 8.
What is a vertical asymptote?
The following function's domain starts at this number: sqrt(x+10)
What is negative 10?
This expression is equivalent to log base 2 of 4 plus log base 2 of 8.
What is log base 2 of 32?
You find this by plugging 0 in for x.
What is the y-intercept?
The solutions to a quadratic equation are called this.
What are Roots, Zeroes, x-Intercepts?
(x^2-16)/(x-4) has this type of discontinuity at
x = 4.
What is a hole?
This method is used to remove the square roots from a radical function's denominator.
What is conjugation?
This expression is equivalent to 5 times log base 3 of 9.
What is log base 3 of 9 raised to 5?
You find these by setting a function equal to 0 and solving for x.
What are x-intercepts?
They are the roots of this quadratic equation:
x^2 - 6x +8 = 0
These two numbers are not in the following function's domain: 1/(x^2 - 9)
What are 3 and -3?
It's the conjugate of sqrt(x) - 3.
What is sqrt(x) + 3?
Exponential and log functions have this relationship.
What is inverse?
