Find the x and y Intercepts y=x^2-1

Problem

y=x2−1

Solution

1. Find the y-intercept by setting x=0 in the equation.

y=0−1

y=−1

2. Find the x-intercepts by setting y=0 in the equation.

0=x2−1

3. Solve for x by adding 1 to both sides of the equation.

1=x2

4. Take the square root of both sides to find the values of x

x=±√(,1)

x=1,x=−1

Final Answer

x-intercepts: *(1,0),(−1,0); y-intercept: *(0,−1)
