Question

Will mark brainliest!! The table shows the outputs, y, for different inputs, x:
(need someone to explain it not just give me the answers)

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) = 8x − 5. Which relation has a greater value when x = 8? (2 points)

Part C: Using the relation in Part B, what is the value of x if f(x) = 19? (5 points)

Answer 1

A. its a function. recall if x1=x2 then f(x1)=f(x2). if you had f mapping 12 to 12 and 12 to 16 it wouldnt be.

B. f(8)=64-5=59>8 so f(x) has a greater value.

C. set 8x-5=19 so 8x=24 and x=3
