Substitute -1 for the variable x.
f(-1) = 2(-1) - 2
f(-1) = -2 - 2
f(-1) = -4
f(-1) = 2(-1) - 2
f(-1) = -2 - 2
f(-1) = -4
When x = -1, the value of the function, f(x) = 2x - 2, is evaluated as: f(x) = -4.
How to Evaluate a Function?
To evaluate a function, plug in the value of x given, and solve accordingly.
Given the function, f(x) = 2x - 2, to evaluate, substitute x = -1 into the function:
f(x) = 2(-1) - 2
f(x) = -2 - 2
f(x) = -4.
