Triangle DEF has verticals D(1, 1), E(2, 0), and F(0, 4). It is transformed by a rotation 180 degrees about the orgin followed by a dilation with a scale factor of 3. Find the coordinates of the verticals of the triangle DEF. 1. D(-1, 1) E(0, 2) F(4, 4)
2. D(-1, -1) E(-2, 0) F(0, -4)
3. D(-3, -3) E(-6, 0) F(0, -12)
4. D(-3, 3) E(6, 0) F(12, 0) ​

b. b < 1 might be the correct answer

birmudah triangle is scaelenn

we have been given a piecewise function which has three parts

we can graph each part one by one.

first part is x+1 which is just like equation y=x+1

restriction with first part is x< 0 so that means we can use any number for x which is less than 0 for example x=-1 and x=-2

now plug x=-1 into y=x+1 to get y

y=x+1=-1+1=0

so the point will be (-1,0)

similarly we get another point (-2,-1)

now we graph a line joining both points but keep in mind that line must be on left side of x=0 because of restriction x< 0

same way we can graph 2nd and third parts

if we have < or > then we use open circle.

if we have < = or > = then we use close circle.

so using above information, final graph can be drawn as:
