+44 Given:
My answer:
1.
2.
As for my solution for 3-5... I do not know how to get them... I tried using the quadratic formula but failed... They say you can solve them by using the vertex formula and you need to graph a parabola in a cartesian plane..
+128475 OK...here's No. 3
y ≥ -2x2 -2x + 1
There's not much to "solve" by hand, here.....a graph of the solution area is more appropriate
Note that the solution area (in blue) lies "above" and just "touching" the parabola (this is indicated by the "≥" symbol)
I don't know if this is what you're looking for, or not.......
+128475 I don't see any problems on here, Phanolo......!!!!
Can you message me with your problem(s) ???
