From my understanding of the lesson, I know the since the parabola is opening downwards, I know 'a' is negative

jdoe0001 · Answer

correct

jdoe0001 · Answer

and a parabola is the graph of a quadratic expression

anonymous · Answer

But I do not understand how to find the linear equation, and I don not fully understand how to get an answer for the question

anonymous · Answer

So what do I do now?

jdoe0001 · Answer

the linear, or the line
notice, from the LEFT towards the RIGHT, is really dropping down
meaning, is a negative slope

anyhow in short,  is really -x
and the quadratic of $-x^2+2$  is also correct for the graph

so....  which set do you think it's?

jdoe0001 · Answer

when x = 1, seems to be the turning point for the graphs

if x > 1   the graph is "something"
if x < 1 the graph is "something else"

what is that "something" and "something else"?

anonymous · Answer

so if it is x>1 the is rising and if the is x<1 the graph is descending?

jdoe0001 · Answer

well... if x > 1, is it rising?
x > 1  means,  x = 2, x =3, x= 4 .....
is it rising at 2 and 3 and 4 and 5 and so on?
