Question

What is the value of f(x)=5− 1/2 x when x=4?

Answer 1

To find the value of f(x)=5− 1/2 x when x=4, substitute x into the function to get f(4) = 5 − (1/2)× 4, which simplifies to f(4) = 3.

Step-by-step explanation:

To find the value of the function f(x)=5− 1/2 x when x=4. This is a simple substitution problem where you need to plug the value of x into the function and calculate. Performing the substitution, we get:

f(4) = 5 − (1/2) × 4

Now, calculate the term with the multiplication:

f(4) = 5 − 2

Finally, subtract 2 from 5:

f(4) = 3

Therefore, the value of f(x) when x=4 is 3.
