Answer:
Range defined as the complete set of possible values of the dependent variable,
or
The range is defined as the resulting y-values we get after substituting all the possible values of x from domain.
Given the function: [tex]f(x)=y = 4x-1[/tex]
Also, x ∈Domain = {-1, 0, 1, 2, 3}
For x = -1;
y = 4(-1)-1 = -4 -1 = -5
For x = 0;
y = 4(0)-1 = 0 -1 = -1
For x = 1;
y = 4(1)-1 = 4-1 =3
For x = 2;
y = 4(2)-1 = 8-1 =7
For x = 3;
y = 4(3)-1 = 12-1 =11
Therefore, the range of the function are the set of all values of y i,e
Range = {-5, -1, 3, 7 , 11}
