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
5 metres, using Pythagorean triples as one is infront one is to the right meaning the distance betweent them would create a triangle so u can calculate it to be 5
Square root of 61 it is something like 7.8 so the nearest integer is C.8 :))
