Which of the following represents a function?
PLEASE HELP 15 POINTS OR BRAINLIEST PLEASE HELP ME

A

Step-by-step explanation:

a function is when the value of x is not repeated

in the other choices you can see that some coordinates have different y-values but some of the x-values are the same

A is the only one in which the x-value is not repeated

A

Step-by-step explanation:

A function is an equation which results in 1 y value for every x value,

Therefore lets eliminate the answers that have repeating x values

A - This is a function, all x values have one output (y value)

B - This is not a function, the x value of 1 repeats meaning theres

more than 1 corresponding output or y value

C - This is not a function, the x value 0 repeats

D - This is not a function, the x value(s) -1 and -2 repeat

Therefore A represents a function and the others do not.

Hope this helps

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

step-by-step explanation:

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

x does not change; y increases by 12.
