y = 3cos(2x) + 2
Step-by-step explanation:
A cosine function is represented ย by y = acos(bx + c) + d
a = amplitude
b = 
c = horizontal shift
d = vertical shift
Given values of a = 3
period = ฯ = 
So, b = 
Horizontal shift c = 0
and d = 2
Therefore, 
will be the equation.

F(x) = -3 * 2 - 6x
So f(-6) = -6 - 6 * -6
= -6 + 36 = 30
So f(-6) = -6 - 6 * -6
= -6 + 36 = 30
