Example Question #81 : How To Find F(X)
If
find 
Given
we must find 
All we do is substitute -4 for the variable x.
So anywhere we see x, we will change to -4.
We get
Example Question #83 : Algebraic Functions
Find 
Given 
we simply substitute.
In this case 
Example Question #81 : Algebraic Functions
If 
When solving a function, we simply substitute the value into the equation. So, we know 
we substitute -4 in for x. By doing that, we get
We now solve using the order of operations. We get
Example Question #81 : How To Find F(X)
If 
To solve a function, we simply substitute the value of x into the equation. So, given that
we will substitute into the function.
Example Question #86 : How To Find F(X)
If 
We know 
Example Question #131 : Functions And Lines
If 
We know 
Example Question #131 : Functions And Lines
Given the following zeros, write out the polynomial function, but don't expand:
To find the polynomial function given the zeros of the function, we must work backwards. If we know that each zero came from a term that was set equal to x, and this term was either added or subtracted to x, we can simply flip the sign on all of the zeros to get the polynomial function they came from:
Example Question #83 : How To Find F(X)
If 
When solving a function, we substitute the value of x into the function itself. So, we know that 
Example Question #90 : How To Find F(X)
If 
When solving a function, we will substitute the value of x into the function itself. We know that
