Graphing Test Review Algebra

Express the relation as a set of ordered pairs and the inverse. xy

Express the relation as a mapping, table and graph. {(-2, 1), (4,5),(-2, 4), (6, 0)} {(-2, 1), (4,5),(-2, 4), (6, 0)}

Identify the domain and range of the relation. {(0, 8),(-1,2),(-2,2),(-3,4)}

Is the equation Linear? xy = 7x + 4 = y ¾ = y xy = 7x + 4 = y ¾ = y

Identify if each relation is a function. {(2,2),(3,2),(4,6),(5,4)} 8y = 7 + 3x

f(x) = -2x + 5 f(x) = -2x + 5 f(1/2)f(x+2)

Rearrange equations into standard form. y = 2x + 6y – 1 = 3( x – 2) y = 2x + 6y – 1 = 3( x – 2)

Name the x and y intercepts. 3x – 2y = 6 3x – 2y = 6 x-intercept = y-intercept =

Use any method to graph the equation. y =- ¾x + 2 y =- ¾x x + 2y = 14 -7x + 2y = 14

Find the next three terms in the sequence. 5, -10, 15, -20, 25…..

Determine if each is an arithmetic sequence. If so, state the common difference. -40, -32, -24, , 1.5, 3, 6, 12

Find the nth term. A 1 = 6 d = 5 n = 11
