Question 1061430: please help i got my portfolio to be handed in tomorrow by 2pm and I missed a class on parabolas i need to find the x intercept and y intercept, can someone please help me? f(x) = 4x^2 + 4x + 6

You find the y-intercept by making

The y-intercept is at ( 0, 6 )
--------------------------------
You find the x-intercepts by making

divide both sides by

Use the quadratic formula
when the form is:

and, also:

-------------------------------
The roots in this case are a pair
of imaginaries called a complex conjugate pair.
There are no actual intersections with the x-axis.
------------------------------------------------
Here's the plot so you can see the y-intercept,
and the fact that there is no intersection with x-axis
