Question

F(x-1) если f(x)=2x-4 как решить?

Answer 1

F(x) = 2x - 4

f(x - 1) = 2(x - 1) - 4 = 2x - 6

Answer 2

To solve the expression f(x-1) when f(x) = 2x - 4, we need to substitute (x-1) into the function f(x).

Replacing x with (x-1) in the expression 2x - 4, we have:

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

Now, let's simplify the expression:

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

Combining like terms:

f(x-1) = 2x - 6

Therefore, the solution is f(x-1) = 2x - 6.
