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

C)

Step-by-step explanation:

let's check all the options:

if x = a

and now with x = a + 2

the answer increased by 16. it is not the right option

if x = a

and now with x = a + 2

the answer increased by 32. it is not the right option

if x = a

and now with x = a + 2

this time, between and there is a difference of 8.

so for this function the statement is true.
