So far, all the expressions you have applied this method to have had a coefficient of 1 on the x2 term. That is a requirement for completing the square. When faced with an expression that does not meet this requirement, you must factor to make it true before applying this method. One important note is that to move a value outside of a parenthesis, it must be multiplied by the same value multiplying the parenthesis. With this note in mind, use the method of completing the square to solve the quadratic equation -2x2 + 12x = 5.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
