Example Questions
Example Question #5 : Function Notation
Find for the following function:
To evaluate , we just plug in a wherever we see an in the function, so our equation becomes
which is equal to
Example Question #7 : Function Notation
Find for the following function:
To find , all we do is plug in wherever we see an in the function. We have to be sure we keep the parentheses. In this case, when we plug in , we get
Then, when we expand our binomial squared and distribute the , we get
Example Question #3 : Function Notation
If , and , for which of the following value(s) will be an odd number?
First, x needs to be plugged into g(x).
Then, the resulting solution needs to be substituted into f(x).
For example,
.
Since 45 is an odd number, 7 is an x value that gives this result. Because both equations subtract an odd number to get the final result, only an odd number will result in an odd result therefore, none of the other options will give an odd result.
Example Question #661 : Algebra Ii
Given , find .
Plug in a for x:
Next plug in (a + h) for x:
Therefore f(a+h) - f(a) = .
Example Question #661 : Algebra Ii
Solve for when .
Does not exist
Plug 3 in for x:
Simplify:
=
= 5
Example Question #3374 : Algebra 1
What is of the following equation?
To complete an equation with a function, plug the number inside the parentheses into the equation for and solve algebraically.
In this case the
Square the 7 and multiply to get
Add the numbers to get the answer .

Example Question #42 : How To Find F(X)
Example Question #13 : Function Notation
If , find .
If then can be rewritten as . Therefore, . Subtracting from both sides of the eqauation gives .
Example Question #661 : Algebra Ii
Evaluate the function for .
To solve for the value of the function at , simply plug in the value in place of every . By doing this, you will be left with the equation:.
Another way to go about the problem is first simplifying the expression so that like terms are collected, so . Then to find , simply plug in the value in place of every . By doing this, you will be left with the equation:.
