So the 4 represents the amplitude of the function. We can also see that because it is a positive number, the graph is even. ⁽⁽The number before the graph type (Sin or Cos) always represents the amplitude. The amplitude is how many units the graph travels up and down from the midline.
The -2 is the midline. This means that the midline is at -2 on the Y-axis. To find the max and min, you then add the amplitude to find the maximum, and subtract to find the minimum. [-6. 2]
To find the period, you divide 2π by the term in front of x. In this case, it's 3, so we do 2π/3. This cannot be simplified further, but in degrees this equals 120°. This means that, with the question asking for 2 full cycles, that the graph will go through 2 full cycles in 240°
Hope this helps, sorry i couldn't sketch the graph for you
If you're trying to solve for y,
5y-4=7
bring over the -4
5y=11
5y/5 = y
11/5 = 2.2
y= 2.2

Step-by-step explanation:
number of residents who have completed some college =5372
number of residents who has completed college and age group 20-29years=1563
1563/5372
=0.29095
Answer:
if -196 was positive, it could be 14 or -14, but because it is negative, it is considered infinity or unknown
