Answer:
(a) The range of the function represents the set of values on the y-axis. We see that function has an absolute maximum, then the range of the function is:
![Ran\{f(x)\} = (-\infty, 4]](https://tex.z-dn.net/?f=Ran%5C%7Bf%28x%29%5C%7D%20%3D%20%28-%5Cinfty%2C%204%5D)
(b) The location of the maximum is represented by its ordered pair. After direct observation, we located this maximum at 
(c) By direct observation we find that the value of
when
is -12.
(d) By direct observation we conclude that the values of
when
are -4.8 and 2.

Answer:
96
Step-by-step explanation:
64 -[16 x (-3) – 2 x{17 – 25 }] I'm going to take a couple of steps that are very small and they can be combines along with other steps. Combine 16*-3
64 - [-48 - 2*(17 - 25)] Combine what is inside (17 - 25)
64 - [-48 - 2*(-8)] Combine -2*-8
64 - [-48 + 16] Combine what is in the brackets.
64 - [-32] Remove the brackets
64 + 32 Combine
96
The trick in this question is the signs.
