1. For the quadratic function f(x) x^2 + x + 4x -1 defined on the interval -6 a)graph the function for the stated domain interval
b)state in the interval over which f(x) is increasing

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)

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
