Question

F = {(x, y): y = 2x + 3} and D= {2, 4, 6} then, find Range of f​

Answer 1

Answer:

R= {7, 11, 15}

Step-by-step explanation:

Since we already know what the Domain is for f (2, 4, 6) we can use that to get the range

Since the domain is also x let's replace x for 2

y=2(2)+3= 4+3=7

One of the range is 7

Replace x for 4

y=2(4)+3= 8+3= 11

One of the other range is 11

Replace x for 6

y= 2(6)+3= 12+3= 15

The last range is 15

So the range is R= {7, 11, 15}

Answer 2

The correct answer is 7,11 an 15 please give me brainlest let me know if it’s correct or not okay thanks bye
