Answer:
x-3
Step-by-step explanation:
f(x) = 3x – 2
g(x) = 2x + 1
(f – g)(x) = 3x-2 - ( 2x+1)
Distribute the minus sign
= 3x-2 -2x -1
= x -3
Answer:
B
y = 3 cos (pi/12x - pi/4) + 17
Step-by-step explanation:
First find the average temperature which is 20 + 14/2 = 17
Find the amplitude
20 - 17 = 3
This means that that at noon, the shift is 3hrs past
