What is the standard form of -5x^2+2x^4-11+x^3+3x

2x^4 + x^3 - 5x^2 + 3x - 11.

Step-by-step explanation:

The standard form is where the exponents are in descending order.

-5x^2+2x^4-11+x^3+3x

= 2x^4 + x^3 - 5x^2 + 3x - 11.

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
