Question

What is f (-2) if f (x) = 1/2x?

Answer 1

To compute f(-2) for the function f(x) = 1/2x, substitute -2 for x to get f(-2) = 1/2(-2), which simplifies to f(-2) = -1.

Step-by-step explanation:

To find f(-2) for the function f(x) = ½x, we simply need to substitute x with -2.

Step-by-step solution:

Substitute x with -2 into the function: f(-2) = ½(-2).

Multiply ½ by -2: f(-2) = -1.

Therefore, f(-2) equals -1.

Answer 2

`f(x) = (1)/(2x) \\~\\~\\f(-2) = (1)/(2\cdot(-2)) \\~\\~\\f(-2) = -(1)/(4) \\~\\~\\f(-2) = -0.25`
