Answer: (10-2) + 1/4
Step-by-step explanation: This expression is 10-2 which si 5 and then 1/4 as great would be bigger than that so you add.
The cut point with the y axis for both graphs occurs when x = 0
We have then:
For f (x):
The cut point with the y axis is:

For g (x):
The cut point with the y axis is:

Therefore, the value of k is given by the vertical displacement of the graph k units.
We have then:

From here, let's clear k:
Answer:
The value of k is -2
