Algebra 1 Name: Relations & Functions Test Review 1 Date: 1)Express the relation {(7, 5) , (8, −2), (7, 6) , (−4, −9), (0, −2)} as a table and a mapping diagram. a)Identify the domain and range of the relation. b)Is the relation a function? For each relation, determine the domain and range. Tell whether the relation is a function. 2) 3) Domain: _________________________ Domain: _________________________ Range: __________________________ Range: __________________________ Is the relation a function? ___________ Is the relation a function? ___________ 4)Determine if each relation is a function. Identify each variable as independent or dependent. 5)The more time you spend studying, the better 6)The faster you drive, the quicker you will your grade will be on your quiz. arriveat your destination. Independent: ______________________________ Independent: ______________________________ Dependent: _______________________________ Dependent: _______________________________ Use the graph below to evaluate the function. 7) a) 𝑓( −8) = d) find x if𝑓( 𝑥) = 6 b) 𝑓( 8) = e) find x if𝑓( 𝑥) = 4 c) 𝑓( −2) = f) find x if𝑓( 𝑥) = 2 Given 𝑓(𝑥) = 2𝑥 − 3 and ℎ(𝑥) = −4𝑥 evaluate the following: 8) 𝑓( −8) 9) ℎ(3) 10) 𝑓( 2) + ℎ(−5) 11) ℎ(0) − 𝑓(1) 12) find x if𝑓( 𝑥) = −31 13) find x ifℎ(𝑥) = −12 Solve for y in each equation. Write y on the left side. 14) 2𝑥 − 6𝑦 = 8 15) 5 − 𝑦 = 𝑥 16) 3𝑦 − 2𝑥 = 9 Make a table and graph. 17) 4𝑦 = 4𝑥 + 8 𝐷 = {−8, −4, 0, 4, 8} 2 18) 𝑦 + 3 = 𝑥 + 5
