Q. Determine the x-intercepts of the following equation.(x−1)(−x−2)=y(1,0) and (−2,0)(0,−2)(0,1) and (0,−2)(1,0) and (2,0)(0,2)(2,0)
Definition of x-intercepts: The x-intercepts of a function are the points where the graph of the function crosses the x-axis. At these points, the value of y is 0.
Set equation equal to zero: Set the equation equal to zero to find the x-intercepts: (x−1)(−x−2)=0.
Solve for x when y=0: To find the x-intercepts, we need to solve for x when y is equal to zero. This gives us two equations to solve: x−1=0 and −x−2=0.
Solve first equation: Solve the first equation: x−1=0. Adding 1 to both sides gives us x=1.
Solve second equation: Solve the second equation: −x−2=0. Adding 2 to both sides gives us −x=2. Multiplying both sides by −1 gives us x=−2.
Identify x-intercepts: The x-intercepts of the equation are the solutions to the equations we found: x=1 and x=−2. Therefore, the x-intercepts are (1,0) and (−2,0).
