Question

If f(x) = 1/2x − 7, then what is f(8)?

Answer 1

-3

Explanation:

Replace x with the given value (8) in the function:

`f(8) = (1)/(2) * 8 - 7 = 4 - 7 = - 3`

Answer 2

f(8) = -3

Explanation:

Now we have to,

→ Find the required value of f(8).

Given function,

→ f(x) = (1/2)x - 7

Then the value of f(8) will be,

→ f(x) = (1/2)x - 7

→ f(8) = (1/2)(8) - 7

→ f(8) = (8/2) - 7

→ f(8) = 4 - 7

→ [ f(8) = -3 ]

Hence, the value of f(8) is -3.
