Atriangle has two sides of lengths 7 and 9. what value could the length of the third side be? check all that apply. a.8 b.5 c.10 d.2 e.13 f.22

A=9
b=7
c>a-b
c>2

c<a+b
c<7+9
c<16
 ⇒c∈(2,16)
⇒ The correct answer is A,B,C,E

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
