Answer:
y = 5 cos ((2π/3)x - 2) + 2
Step-by-step explanation:
Cosine function takes a general form of y = A cos (Bx + C) + D
Where
A is the amplitude
2π/B is the period
C is the phase shift ( if -C, then phase shift right, if +C phase shift left)
D is the vertical displacement (+D is above and -D is below)
Given the conditions of the function to build and the general form, we can write:
** Note: period needs to be 3, so 2π/B = 3, hence B = 2π/3
Now we can write:
y = 5 cos ((2π/3)x - 2) + 2
first answer choice is right.
Answer:
66a
Step-by-step explanation:
m=-6 and y-int of (0,5) gives you y = -6x + 5.
Looking through those other equations, you're looking for variations of that equation.
#1 is NOT.
#2 IS, because -6x + 5 is the same as 5 - 6x.
#3 is NOT.
#4 is NOT.
#5 is NOT.
#6 is NOT.
It looks like #2 is the only one.
