.
Find .
Finding means plugging in in place of x into the function . In this case, we are told that , so we are multiplying by 2 and then adding 17:
order of opperations tells us to first multiply:
and now add:
Example Question #42 : Algebraic Functions
.
Evaluate .
Evaluating means plugging 5 in for x in the function . In this case, we are told that , so that is what we will do to 5 - multiply by 2, then square the product:
order of opperations [PEMDAS] tells us that first we will be doing what is in the parentheses, so we will multiply first:
now we can square 10 for the final answer:
Example Question #43 : Algebraic Functions
.
Find .
Evaluating means plugging in 2 for x in the function . In this case we are told that , so that is what we'll do with 2:
Order of opperations [PEMDAS] tells us to do parentheses first, but no opperations are taking place in parentheses. Next we will do exponents:
The next step in order of opperations is multiplication, so we will next multiply 3 and 4:
finally we will subtract:
Example Question #42 : How To Find F(X)
If is the reciprocal of the following function what is ?
The question is asking for the reciprocal.
The reciprocal can be found by flipping the numerator and the denominator, effectively dividing 1 by the number.
becomes .
*Always remember what the question is asking.
Example Question #1 : Understand Functions: Ccss.Math.Content.8.F.A.1
Find .
Undefined
This question demonstrates that complicated functions are not complicated at every point.
To solve the function at x=1, all that is necessary is familiarity with the operations used.
