Revolt · Accepted Answer

2

Question 8

Which best describes the roots of the function h(x) = x3 – 4x2 – 3x + 18?

Revolt · Accepted Answer

2 real number solutions

Question 9

The function f(x) = –x3 + 2x2 – x + 5 is graphed on a coordinate grid. Which statements accurately describe the end behavior of the graph of the function?

Revolt · Accepted Answer

As x approaches negative infinity, y approaches positive infinity. As x approaches positive infinity, y approaches negative infinity.

Question 10
