Answer: {[tex]{ -5 , -1 , 3 , 7 , 11 }[/tex] }
Step-by-step explanation:
Given :
[tex]f(x) = 4x - 1[/tex]
domain = { [tex]-1 , 0 , 1 , 2 , 3[/tex] }
To find the range , we will substitute the domain as the value of x into the function given , that is
when x = - 1
[tex]f(x) = 4 (-1) - 1[/tex]
[tex]f(x) = -5[/tex]
when x = 0
[tex]f(x) = -1[/tex]
when x = 1
[tex]f(x) = 4(1) - 1[/tex]
[tex]f(x) = 3[/tex]
When x = 2
[tex]f(x) = 7[/tex]
when x = 3
[tex]f(x) = 11[/tex]
Therefore: the range = [tex]{ -5 , -1 , 3 , 7 , 11 }[/tex]
