Describe the graph of the function.y = |x – 4| – 7
juin [17]
This is always ''interesting'' If you see an absolute value, you always need to deal with when it is zero:

(x-4)=0 ===> x=4,

so that now you have to plot 2 functions!

For x<= 4: what's inside the absolute value (x-4) is negative, right?, then let's make it +, by multiplying by -1:

|x-4| = -(x-4)=4-x
Then:

for x<=4, y = -x+4-7 = -x-3

for x=>4, (x-4) is positive, so no changes:

y= x-4-7 = x-11,

Now plot both lines. Pick up some x that are 4 or less, for y = -x-3, and some points that are 4 or greater, for y=x-11

In fact, only two points are necessary to draw a line, right? So if you want to go full speed, choose:

x=4 and x= 3 for y=-x-3

And just x=5 for y=x-11

The reason is that the absolute value is continuous, so x=4 works for both:

x=4===> y=-4-3 = -7

x==4 ====> y = 4-11=-7!

abs() usually have a cusp int he point where it is =0

Hope it helps, despite being this long!

Carolyn says that point A and point B represent opposite integers. a. What is the opposite of the integer represent by point A?
zysi [14]

we are given

point-A= -7

point-B=8

(a)

opposite of point-A is negative of point-A value

so,

opposite of point-A is -(-7)

opposite of point-A is 7

opposite of point-B is negative of point-B value

so,

opposite of point-B is -8

opposite of point-B is -8

(b)

we can see that

opposite of point-A is 7

opposite of point-B is -8

they are not equal

so, this argument is FALSE.......Answer
