Question

I’m so confused. can someone please help

Answer 1

k = - 6

Explanation:

Given a function f(x), then a horizontal translation parallel to the x- axis is denoted by

f(x + k)

If k > 0 then shift of k units left

If k < 0 then shift of k units right

Here the shift is 6 units to the left, from 4 to - 2, hence

k = 6
