When x increases from a to a + 2, y increases by a difference of 8. for which functions is this statement true? a) y = 2(4)^x b) y = 2(8)^x c) y = 4x + 2 d) y = 8x + 2

That would be Option C.

Step-by-step explanation:

Lets look at y = 4x + 2:-

Let x = a then y = 4a + 2

Now if x in creases to a +2,  y = 4(a +2) + 2 = 4a + 8 + 2

= 4a + 10.

(4a + 10) - (4a + 2) = 8  ,  so this is the required expression, y = 4x + 2.

answer: 59
