Q. The equation s=(t+3)2(t+2)(t+1)(t)(t−1) is graphed on the st-plane. What is the product of the unique t-intercepts of the graph?□
Identify t-intercepts: Identify the t-intercepts of the graph.The t-intercepts occur when s=0. To find the t-intercepts, we set the equation equal to zero and solve for t.0=(t+3)2(t+2)(t+1)(t)(t−1)The t-intercepts are the solutions to this equation.
Find unique solutions for t: Find the unique solutions for t.The equation is already factored, so we can see the solutions directly from the factors:t+3=0⇒t=−3 (this root is squared, but it still counts as one unique intercept)t+2=0⇒t=−2t+1=0⇒t=−1\newlinet−1=0t-1 = 0t−1=0⇒\Rightarrow⇒t=1t = 1t=1\newlineThese are the unique t−t-t−intercepts of the graph.
Calculate product of t-intercepts: Calculate the product of the unique t-intercepts.\newlineThe product of the t-intercepts is found by multiplying them together:\newlineProduct = (−3)×(−2)×(−1)×(0)×(1)(-3) \times (-2) \times (-1) \times (0) \times (1)(−3)×(−2)×(−1)×(0)×(1)
Simplify the product: Simplify the product.\newlineSince one of the factors is 000, the product of the ttt-intercepts is 000.\newlineProduct = 000
