Both problems give you a function in the second column and the x-values. To find out the values of a through f, you need to plug in those x-values into the function and simplify!

You need to know three exponent rules to simplify these expressions:

1)

** **The

**negative exponent rule** says that when a
base has a negative exponent, flip the base onto the other side of the
fraction to make it into a positive exponent. For example,

.

2)

**Raising a fraction to a power **is the same as separately raising the numerator and denominator to that power. For example,

.

3) The

**zero exponent rule**<span> says that any number
raised to zero is 1. For example,

.

</span>

**Back to the Problem:**

Problem 1

The x-values are in the left column. The title of the right column tells you that the function is

. The x-values are:

<span>

**1) x = 0**</span>Plug this into

to find letter a:

<span>

**2) x = 2**</span>Plug this into

to find letter b:

<span>

**3) x = 4**</span>Plug this into

to find letter c:

<span>

Problem 2

</span>The x-values are in the left column. The title of the right column tells you that the function is

. The x-values are:

<span>

**1) x = 0**</span>Plug this into

to find letter d:

<span>

**2) x = 2**

</span>Plug this into

to find letter e:

<span>

**3) x = 4**

</span>Plug this into

to find letter f:

<span>

**Answers: ****a = 1****b = **</span>

<span>

**c = **</span>

**d = 1****e = ****f = **
