Which of the following represents the range of the function f(x) = -4x + 1 for the domain (-5, -1, 0, 2, 10)
(-39, -7, 1, 5, 21)
(-41, -9, 1, 5, 21)
(-19, -3, 1, 5, 21)
(-41, -9, -3, -19)
Solution:
f(x) = -4x + 1
Domain are the values which serve as inputs to the function. The output of the function is called the range of the function.
When x = -5
f(x) = -4(-5) + 1 = 21
When x = -1
f(x) = -4(-1) + 1 = 5
When x = 0
f(x) = -4(0) + 1 = 1
When x = 2
f(x) = -4(2) + 1 = -7
When x = 10
f(x) = -4(10) + 1 = -39
The range of the function is [-39, -7, 1, 5, 21]
Which of the following represents the range of the function f(x) = -4x + 1 for the domain (-5, -1, 0, 2, 10)
