Question

Can someone help me with this question?

a. x^2 - x - 2 = 0
b. x^2 - x = -1

How would I draw these in a graph??

Answer 1

well you can use a table of values say

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

and find the matching y values, plot the points...

that's one method

Answer 2

Is that the only method?

Answer 3

find the zeros, find the y intercept, find the vertex. then connect the dots

Answer 4

Thanks

Answer 5

I highly doubt you teacher wanted you to plot random points. Do you know how to find all the things I mentioned?

Answer 6

I'm home schooled so yeah.... Not really....
