The function g(x) has an average change of 2.25 on the interval -2 ≤ x ≤ 6. If g(-2)= -7 then which of the following is the value of *(6)? 1.) 11
2.) 9
3.) -15
4.) -8

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
