What is the vertex of the absolute value function defined by ƒ(x) = |x - 7| + 1?
2 answers:
The absolute value function, known as the modulus function, is represented by a v-shaped graph, or a modulus graph. So the graph looks like a V.
Let the vertex point be S.
To find the coordinates of the vertex S, you follow those steps:
First, to find the x of the vertex, you takes what's between the absolute value and make it =0
x - 7 = 0
Add 7 in both sides to get the variable x alone on a side and its value on the other side:
x - 7 + 7 = 0 + 7
x = 7
So S(7;y)
Now to find y, we replace x by its value and do the calculus:
|x - 7| + 1 = |7 - 7| + 1 = 0 + 1 = 1
So S(7;1).
I've added a picture of the graph represented this equation under the answer.
Hope this Helps! :)

Answer:
(B) Time (min) 2 , 3 , 7 , 9
Temperature (°C) 60.6 , 64.3 , 79.1 , 86.5
Step-by-step explanation:
The rate of change is found by using the formula for slope:
For option A, this gives us
m =(64.4-61.0)/(3-2) = 3.4/1 = 3.4
This is not more than relationship A.
For option B, we have
(64.3-60.6)/(3-2) = 3.7/1 = 3.7
This is more than relationship A.
For option C, we have
(65.3-61.8)/(3-2) = 3.5/1 = 3.5
This is not more than relationship A.
For option D, we have
(64.6-61.0)/(3-2) = 3.6/1 = 3.6
This is not more than relationship A.
