we just started learning this
I'm having troubles with it. I know b<0, but not a
Oh ,, I posted the wrong question
Though, the previous one is also the question I don't know. Just do it later.
if x was zero then b would be........
I told you I know b<0. I don't know range of value for a only
a has to be postive
we know b is negative ... x is postive /...... x^2 is postive ......-x^2 is negative... so we have two negative terms but still ax is reaching above the x axis... we x is postive ..... so a must be postive to make ax postive plus ax has to be greater than -x^2+b
OMG, I've never though in that way. Thank you!
cool but b could be so large like -1000000 that it would never go above the line
