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,
\(f(x) = 2x - 9\\f(-3)=2.(-3)-9\\f(-3)=-6-9\\f(-3)=-15
eq 15\)
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,
\(f(x) = 2x - 9\\f(-1)=2.(-1)-9\\f(-1)=-2-9\\f(-1)=-11\)
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,
\(f(x) = 2x - 9\\f(0)=2.(0)-9\\f(0)=0-9\\f(0)=-9\)
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,
\(f(x) = 2x - 9\\f(2)=2.(2)-9\\f(2)=4-9\\f(2)=-5
eq5\)
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,
\(f(x) = 2x - 9\\f(3)=2.(3)-9\\f(3)=6-9\\f(3)=-3\)
This option is correct.
