: y = 25 - x^2
: y = (5 + x)(5 - x)
: It intersect x-axis at x = 5. It cannot intersect x-axis at x = 6
: Or am I interpreting your problem wrong.....
Thanks for your reply.
Yea I don't get it too.Because when I work it out by hand, x=5, however, on excel, the graph shows that x=6 when y=0.
Because I'm calculating the consumer surplus, and the graph extends all the way to the negatives, do I have to account for that too?
