### Example Question #3371 : Algebra 1

.

Find .

**Possible Answers:**

**Correct answer:**

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 : How To Find F(X)

.

Evaluate .

**Possible Answers:**

**Correct answer:**

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 #41 : How To Find F(X)

.

Find .

**Possible Answers:**

**Correct answer:**

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 ?

**Possible Answers:**

**Correct answer:**

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 #3 : Functions
