idk what i keep doing wrong
OpenStudy (amistre64):
-x^2-3x+9 the mirror image over the x axis is: x^2+3x -9; so whatever the y value for this is at the vertex, change its sign
OpenStudy (amistre64):
(-3/2,-(y)) 9 9(2) 9(4) 9-18 -36 -45 --- - ----- - ---- = ---------- = ---- ; opposite that maybe 4 2(2) 1(4) 4 4
