When evaluating the power of a product (𝑒𝑥: (2 × 3)2 = 22× 32 = 4 x 9 = 36), you can apply the exponent to both numbers that you are multiplying.


When evaluating the power of a quotient (ex: (7813) 3

=781333 = 4745522197 = 216 ), you can apply the exponent to both numbers to be divided.

Evaluate order of operations expressions that involve some or all of the exponent laws.

Unit 4(13%)

Know what a relation is.

Create a table of values (input/output table) given a relation.

Given a pattern (diagram) write a relation to represent it.

Write a relation (equation) given a table of values.

Given a relation, evaluate for a given number (ex: given P = 2n + 1, find P when n = 3  Ans: P = 2 (3) + 1 = 6 + 1 = 7).

Solve problems by creating a table of values, an equation and solving.

Given a graph, determine if a relation is linear.

Given a table of values, determine if a relation is linear.

Given an equation, determine if a relation is linear.

Create a table of values given an equation and values for x.

Word problems.

Know the three types of lines and their equations: Horizontal (Eqn: y = a number), Vertical (Eqn: x = a number) and Oblique (Equation has 2 variables).

Write the equation of horizontal and vertical lines given a graph.

Recognize the alternate form for an oblique line (ex: 2x + 2y = 7).

Given any graph and any linear equation, match the equation to the graph.

Use a graph to gain information (extrapolate and interpolate). You may have to extend the graph to find missing information (see pgs 195 – 198).
