Question

If f(x) = − 5, what is f(8.6)?

3
4
8
9

Answer 1

4

Explanation:

|8.6|-5=f(x)

(round) |9|-5=f(x)

f(x)=4

Answer 2

f(x) = -5.

This function is independent of x. There is no term associated with x on the function.

Therefore f(8.6) = -5 still.

f(8.6) = -5.

From the options there is no answer.

OR

you can write f(x) = -5

f(x) = -5x⁰ because x⁰ = 1.

f(8.6) = -5*8.6⁰ = -5 *1, 8.6⁰ = 1
(Any non zero raised to power zero is 1)
f(8.6) = -5

NO ANSWER from the options given.
