Q. Determine the x-intercepts of the following equation.(x+1)(x−3)=y(0,−1) and (0,3)(−3,0)(0,3)(0,−3)(−1,0) and (3,0)(−1,0) and (−3,0)
Identify x-intercepts: Identify the x-intercepts. The x-intercepts occur where the graph of the equation crosses the x-axis, which is where y=0. So, we set y to 0 and solve for x in the equation (x+1)(x−3)=y. 0=(x+1)(x−3)
Solve for x: Solve the equation for x.We have 0=(x+1)(x−3).To find the x-intercepts, we set each factor equal to zero and solve for x.x+1=0 or x−3=0
Find first x-intercept: Find the first x-intercept.Solving x+1=0 gives us x=−1.So, one x-intercept is (−1,0).
Find second x-intercept: Find the second x-intercept.Solving x−3=0 gives us x=3.So, the second x-intercept is (3,0).
