The function f(x) = –x2 – 4x + 5 is shown on the graph. On a coordinate plane, a parabola opens down. It goes through (negative
5, 0), has a vertex at (negative 2, 9), and goes through (1, 0). Which statement about the function is true? The domain of the function is all real numbers less than or equal to −2. The domain of the function is all real numbers less than or equal to 9. The range of the function is all real numbers less than or equal to −2. The range of the function is all real numbers less than or equal to 9.
First let's find the result of the sum: 30 + 40 + 70 = 140 Now let's review the operations of each one: Jillian added 30and40and then 70: 30 + 40 = 70 70 + 70 = 140 Samuel added 30 and 70 and then 40 30 + 70 = 100 100 + 40 = 140 answer both are correct. Conclusion: the order of the factors does not alter the product.
