f(x) = x^2 – 2

x:  -3, -2, -1, 0, 1, 2, 3

1. Substitute all of the values that you have for x into the equation

2. Solve for y.

3. Graph.

 

ORDER OF OPERATIONS

PEMDAS, an acronym most students learn as early as the second grade. PEMDAS describes the order in which operations are organized.

(    )Parentheses    2^x Exponents x, *, (    ) Multiplication

÷, / Division    + Addition    - Subtraction

These operations are to be used with you evaluate an expression.

Examples

4(3x +5) – 12 —-> 12x + 20 – 12 —–>  12x – 8 —->  12x/12 = -8/12 —>

x = -1/3

MONOMIALS RULE!

Rules to remember for monomials

• When you multiply coefficients, you add exponents
• When you divide coefficients, you subtract exponents
• When you raise an exponent to a power, you multiply exponents
