Answer:
Opt. D.
Step-by-step explanation:
To solve this problem we need to focus our attention in the abs(x-1) function,
If x>1, then abs|x-1|= x-1, if x<1 then abs|x-1|= 1-x. And in the two intervals, the function opens upwards.
But our function has -3 multiplying abs|x-1|, This means that our function opens downward.
The vertex point can be found when x=1, since abs(x-1)=0. this gives f(1)=12
Answer:
The student incorrectly simplified .
Thus, option D is correct.

Step-by-step explanation:
The formula to determine the Perimeter of a rectangle of width w and length l is expressed as:
In other words, the perimeter can be determined by multiplying the length and width by 2 and adding the result.
In our case, the dimensions of a rectangle are and
.
Here is the student's solution:
The student made an error in calculating , because
are not like terms.
Hence, can not be simplified to
Therefore, the student incorrectly simplified .
Thus, option D is correct.
