The table shows the outputs, y, for different inputs, x: Input (x) 1 2 3 4
Output (y) 5 5 7 9

Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Part B: Compare the data in the table with the relation f(x) = 2x − 8. Which relation has a greater value when x = 4? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 34? Show work for full credit. (5 points)

yes, this data represents a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.

Step-by-step explanation:

data in the table : when x = 9this is already a point on the table (9,12)...so the value on the table, when x = 9, is 12

f(x) = 5x + 14when x = 9

f(9) = 5(9) + 14

f(9) = 45 + 14

f(9) = 59

the relation with the greater value would be : f(x) = 5x + 14

f(x) = 5x + 14when f(x) = 64

64 = 5x + 14

64 - 14 = 5x

50 = 5x

50/5 = x

10 = x <==

hope this helps :)

table 3 represents a direct variation function. : )

can you make your screen more see able?

then i might be able to .
