Question

If f(x)=8-5x find each value
14. f(2-k)

Answer 1

Answer: f(2-k) = 5k - 2

Explanation:

To solve for f(2-k), we will substitute 2 - k into x in the given function.

Then we will simplify.

Given:

f(x) = 8 - 5x

Substitute:

f(2-k) = 8 - 5(2-k)

Distribute:

f(2-k) = 8 - 10 + 5k

Combine like terms:

f(2-k) = -2 + 5k

Reorder terms:

f(2-k) = 5k - 2
