Which of the following could be the graph of y=x^2-2

The graph attached is the answer

Step-by-step explanation:

The given equation is in the form

The equation is parabola as shown in the graph

Roots are

Domain of the euation- All sets of real number

Range of the equation -

In this graph the point cut the x-axis

(-1.414,0) and (1.414,0)

point cut the y-axis (0,-2)

therefore, the graph attached is the require graph

the answer is d

step-by-step explanation:

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
