For this case we have the following function:
 y = -6cos4x
 The function is defined for all values of x, therefore, the domain is:
 (-inf, inf)
 The range of the function is:
 For x = 0
 y = -6cos (4 (0))
 y = -6cos (0)
 y = -6 (1)
 y = -6
 For x = pi / 4
 y = -6cos (4 (pi / 4))
 y = -6cos (pi)
 y = -6 (-1)
 y = 6
 The range of the function is:
 [-6, 6]
 The amplitude of the function is:
 6
 Answer:
 
Domain: (-inf, inf)
 
Range: [-6, 6]
 
Amplitude: 6

Tatiana [17]

Step-by-step explanation:

By Remainder Theorem, f(5) = 91.

=> (5)³ - 4(5) + k = 91

=> 125 - 20 + k = 91

=> 105 + k = 91

=> k = -14.
