I have an equation right here it's a second degree equation it's a quadratic and I know it's graph is going to be a parabola this was a review that means it looks something like this or it looks something like that because the coefficient on the x squared term here is positive and it's going to be an upwardopening parabola and I am curious about the vertex of this parabola and if I have This is a quadratic function of form y=ax^2bxc, with a=1, b=4 and c=5 The graph will be a parabola Since a is positive, the arms go up To find the yintercept, let x = 0 and find y = c = 5 To find the xintercepts, let y = 0 and use either factorizing or the quadratic formula to find the roots x = 5 or x = 1 To find the turning point, set the derivative to zero therefore2xRelated Queries rotate y=x^2 from x=1 to 1 about the yaxis;

How many solutions does y=x^2+4x+5 have
How many solutions does y=x^2+4x+5 have- Here is a sketch of the bounded region we want to find the area of Show Step 2 For this problem we were only given one limit on x x ( ie x = 4 x = 4 ) To determine just what the region we are after recall that we are after a bounded region This means that one of the given curves must be on each boundary of the regionYou can put this solution on YOUR website!
