The Antidifference Operator
# The Antidifference Operator
We have already seen with The Difference Operator that if $f$ is a real-valued function then the difference operator applied to $f$ is $\Delta f = f(x + 1) - f(x)$ which is an analogue to the derivative $\frac{df}{dx}$ of $f$.
We will now look at another calc... |

$6 x - 2 y = - 16$ and
$4 x + 4 y = - 32$
or
$2 x + 2 y = - 16$
or
$x + y = - 8$
Adding up the equations $6 x - 2 y = - 16$ and $2 x + 2 y = - 16$
We get
$6 x - 2 y + 2 x + 2 y = - 16 - 16$

```Unit 2 Review Sheet
Combining Like Terms:
Like terms have the same variable raised to the same power.
We can only add or subtract like terms. We cannot add or subtract unlike terms.
Example: 5x + 3y + 6x +2y = 11x + 5y
Note: When there is subtraction in an expression, you should change it to addition to prevent

# What Is Domain And Range In Mathematics?
## What is domain and range examples?
Example 2: The domain is the set of x -coordinates, {0,1,2}, and the range is the set of y -coordinates, {7,8,9,10}. Note that the domain elements 1 and 2 are associated with more than one range elements, so this is not a function.

Question 1.
If the cost of 9 m cloth is ₹378, find the cost of 4 m cloth.
Solution:
∵ Cost of 9 m of cloth = ₹378
∴ Cost of 1 m of cloth = ₹ $$\frac{378}{9}$$ = ₹42
∴ Cost of 4 m cloth = ₹42 × 4 = ₹168
