Answer:
-1 ≤ x ≤8 (don't care about the equal sign)
Step-by-step explanation:
-6+4≤2x≤12+4
=-2≤2x≤16
=-1≤x≤8
Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:

Hence, the answer is:
f(x) = 4cos(8/3 x) - 3
