Question

How can I find the x-intercept in the function : -x^2+1

Answer 1

=-x^2+1
-x^2=-1
x^2=1
\[\sqrt{x^{2}}=\sqrt{1}\]
x=1

Answer 2

thank you. do you know how to find the ned behavior for it?

Answer 3

end behavior

Answer 4

End behavior? I didnt really get that term. Are you using the right term?

Answer 5

Oh sorry i got ya what you were asking.

Answer 6

ok

Answer 7

To determine the end behavior of an equation the degree and the leading coefficient helps us. A graph is plotted and by checking the leading coefficient in our case which is negative in -x^2, so the end behavior of the function would be
\[F(X)\rightarrow-\infty, as X \rightarrow-\infty\]\[F(X)\rightarrow-\infty, as X \rightarrow+ \infty \]
