Question

i cannot figure this out still nor do i undertsand this i need to graph this function which is a paroble (think I spelled it correctly), anyway here it is Function y=-3x^2-6x-5

Answer 1

what are you confused about?

Answer 2

if all else fails, pick some numbers for x and find the y. plot the (x,y) pairs
and connect the dots

try x= -3, -2, -1, 0, 1, 2, 3

Answer 3

i can make the vertex no problem

Answer 4

if you know the vertex, pick x values near the vertex (on both sides)

Answer 5

but when i go and plug the values into the formula is hwne i have a problem

Answer 6

y=-3x^2-6x-5

when x=0, what is y ?
