Answer:
k = 3
Step-by-step explanation:
The graph P(x) is a square root function. It has a vertex of (0,0) and has the following points:
x f(x)
0 0
1 1
2 √2
3 √3
4 2
P(x) appears to be the function √x.
The image of l(x) changes the points of the function to
x f(x)
0 0
1 3
2 3√2
3 3√3
4 6
You can divide the function values of l(x) by P(x).
3/1 = 3
6/2 = 3
The scale factor for the dilation is 3. k= 3.
