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.
