To find f(-4), we can substitute -4 into the function:

f(-4) = 2(-4) - 1

Simplifying this expression:

f(-4) = -8 - 1

f(-4) = -9

Therefore, f(-4) is equal to -9.

To find f(0), we can substitute 0 into the function:

f(0) = 2(0) - 1

Simplifying this expression:

f(0) = 0 - 1

f(0) = -1

Therefore, f(0) is equal to -1.

To find f(4), we can substitute 4 into the function:

f(4) = 2(4) - 1

Simplifying this expression:

f(4) = 8 - 1

f(4) = 7

Therefore, f(4) is equal to 7.
