Find the range of the function f(x)=4x−1 for the domain {−1,0,1,2,3}
To find the range of the function, f(x) = 4x - 1, we can substitute each value in the domain {−1, 0, 1, 2, 3} into the function and list the corresponding outputs.
For x = -1:
f(-1) = 4(-1) - 1 = -4 - 1 = -5
For x = 0:
f(0) = 4(0) - 1 = 0 - 1 = -1
For x = 1:
f(1) = 4(1) - 1 = 4 - 1 = 3
For x = 2:
f(2) = 4(2) - 1 = 8 - 1 = 7
For x = 3:
f(3) = 4(3) - 1 = 12 - 1 = 11
So, the range of the function f(x) = 4x - 1 for the domain {−1, 0, 1, 2, 3} is {-5, -1, 3, 7, 11}.
