Choose 4 values for x to complete the function f(x)=x-7.

6, 8, 3, 10 will be the answer for this question

F(x) = -3
domain is 4 and i think -7 is the range

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 

3you can not round up to four, as there was not a full payment for the fourth night, so uou would round down to 3
