Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = 4x2 – 8x – 3.
2 answers:
Axis of symmerty from form
ax²+bx+c is -b/2a
the axis of symetry is the x value of the vertex so just put the axis of symetry for x an evaluate
4x²-8x-3
-b/2a=-(-8)/(2*4)=8/8=1
input for x
4(1)²-8(1)-3=4-8-3=-7
(1,-7) is vertex
A is answer

Step-by-step explanation:
4a+3b-(-2a-3b)
=4a+3b+2a+3b
=6a+6b
=6(a+b)
7 - 4 3/4
= 28/4 - 19/4 = 9/4
Answer is 2 1/4 or 2.25.
I'm not really sure If I would be much help but I'll try best k? (cries a little) So you do 100
+ 6.0
+ 4.0
