Determine if the sequence could be arithmetic. if so, give the common difference. -6, -9, -12, -15, -18… i need so if someone can it would mean alot!

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
