The table shows the outputs, y, for different inputs, x: Input (x) 6 12 15 25
Output (y) 14 15 15 16

Part A: Does the data in this table represent a function? Justify your answer.

Part B: Compare the data in the table with the relation f(x) = 7x − 15. Which relation has a greater value when x = 6?

Part C: Using the relation in Part B, what is the value of x if f(x) = 6?

okay, if you need all you need to do is ask, and i'll do my best to assist you.

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
