Look at the picture.
The domain is read from the x axis.
Domain: (-5, 5]
The range is read from the y axis.
Range: [-4, 4]
Max: 4
Min: -4
Continuous
y-intercept: 0
x-intercepts: 0 and 5
f(5) = 0 therefore 7 * f(5) = 7 * 0 = 0
----------------------------------------------------------------------------------
Domain: (0, 12)
Range: (0, 8]
Max: 8
Min: not exist
Interval of increase: (0, 3]
Interval of decrease: [9, 12)
