Question

F(5),f(-1),если f(x)=x-1

Answer 1

f(x) = x - 1,

f(5) = 5 - 1 = 4,

f(-1) = -1 - 1 = -2

Answer 2

To find the values of f(5) and f(-1) when f(x) = x - 1, you simply need to substitute the given values of x into the function.

1. For f(5): f(5) = 5 - 1 = 4

So, f(5) = 4.

2. For f(-1): f(-1) = (-1) - 1 = -2

So, f(-1) = -2.
