Which of the following best describes how the y values are changing over each interval? x y 1 2 2 4 3 8 4 16 5 32 a) they are increasing by 2 each time. b) they are increasing by 4 each time. c) they are being multiplied by 2 each time. d) they are being multiplied by 4 each time.

f(x+3) = -5x -9

Step-by-step explanation: Start by substituting (x+3) for x. When you do this, you'll get the answer

f(x + 3) = -5 (x + 3) + 6

When you multiply out the (x + 3) by the -5, you'll get an answer of (-5x -15), which gives you the full equation

f(x + 3) = -5x -15 +6

Now, you just have to combine the like terms of -15 and +6, or, 6-15, to get -9.
