Consider the function f (x) = 2x -1 . What is the output if the input is x = -3

1 answer

To find the output of the function f(x) when the input is x = -3, you substitute -3 for x in the function:

f(-3) = 2(-3) - 1
f(-3) = -6 - 1
f(-3) = -7

Therefore, the output of the function f(x) when the input is x = -3 is -7.
