Answer:
k = - 6
Step-by-step 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

Answer:
<em>Riko is wrong because she uses the wrong formula.</em>
Step-by-step explanation:
Given the coordinate points (-2, -3) and (2, -5)
We are to find the distance between the two points
Using the formula:
D = √(x2-x1)²+(y2-y1)²
From the coordinates x1 = -2, y1 = -3, x2 = 2 and y2 = -5
Substitute
D = √(2-(-2))²+(-5-(-3))²
D= √(4)²+(-2)²
D = √16 + 4
D = √20
D = √4*√5
D = 2√5
<em>This shows that Riko is wrong because she uses the wrong formula.</em>
