Question

y=-2x^2+4x-3
x=-4 / 2-2

help me finish please!

Answer 1

x = -4/-4; so x=1

what does y = when x=1?

Answer 2

thats what I am having trouble with

Answer 3

when x=1 that pretty much means we can ignore any of the xs; since 1 times anything is itself

Answer 4

y=-2+4-3

Answer 5

since this quadratic starts out with a negative number: that -2x^2 part

its vertex is a high point
