Answer:

f(-1)=-11

f(0)=-9

f(3)=-3

Step-by-step explanation:

We have f(x) = 2x - 9,

  • f(-3) is the value of the function f when x=-3, then you have to replace f(x) with x=-3,

[tex]f(x) = 2x - 9\\f(-3)=2.(-3)-9\\f(-3)=-6-9\\f(-3)=-15\neq 15[/tex]

This option is incorrect.

  • f(-1) is the value of the function f when x=-1, then you have to replace f(x) with x=-1,

[tex]f(x) = 2x - 9\\f(-1)=2.(-1)-9\\f(-1)=-2-9\\f(-1)=-11[/tex]

This option is correct.

  • f(0) is the value of the function f when x=0, then you have to replace f(x) with x=0,

[tex]f(x) = 2x - 9\\f(0)=2.(0)-9\\f(0)=0-9\\f(0)=-9[/tex]

This option is correct.

  • f(2) is the value of the function f when x=2, then you have to replace f(x) with x=2,

[tex]f(x) = 2x - 9\\f(2)=2.(2)-9\\f(2)=4-9\\f(2)=-5\neq5[/tex]

This option is incorrect.

  • f(3) is the value of the function f when x=3, then you have to replace f(x) with x=3,

[tex]f(x) = 2x - 9\\f(3)=2.(3)-9\\f(3)=6-9\\f(3)=-3[/tex]

This option is correct.
