Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = 4x2 – 8x – 3.

my question is Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = 4x2 – 8x – 3. i really need help with this question  

how many times does the quadratic function below intersect the x-axis

y=x^2+3x+15

the graph of 2x+y=2 is a line L through the points (0,2) and (1,0). Describe the graph of 2x+y is greater than or equal to 2.

I've been stuck on this question and I do not know how to answer it.   The options are:   A) Half-plane containing the L as its boundary and containing the origin. B)...

The points -8,-2 -8,2 -4,2 and -4,-2 make what kind of shape

I don’t know how to solve this help

With slope of 3/5 and passing through the origin

i think I need to graph this but it says I need to have it into ax+by=c formula!
