Find the y-intercept of the parabola y=x^2-3 Simplify your answer and write it as a proper fraction improper fraction, or inte square

To find the y-intercept of the parabola $y=x^{2}-3$, we need to set $x=0$ and solve for $y$.<br /><br />Substituting $x=0$ into the equation, we get:<br />$y = (0)^{2} - 3$<br />$y = -3$<br /><br />Therefore, the y-intercept of the parabola $y=x^{2}-3$ is $-3$.
