consider the function f(x) = 2x - 1

Question

what is the output if the input is x = -3

Answer 1

To find the output of the function when the input is x = -3, we simply substitute -3 in place of x in the function and solve:

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

Thus, the output of the function f(x) = 2x - 1 when the input is x = -3 is -7.
