Answer:
Step-by-step explanation:
y-intercept is -4
Answer:
(0, -2)
Step-by-step explanation:
The y-intercept is where the graph crosses the y-axis when x = 0. As shown in the graph, when x = 0, y = -2, so your answer is (0, -2).
(x+1)(2x+1)(x-2)
= (2x+1)(x+1)(x-2)
= (2x+1)(x² -x - 2)
= 2x³ - 2x² - 4x + x^2 - x - 2
= 2x³ - x² - 5x - 2
Answer: 2x³ - x² - 5x - 2
