f(x) = x³ + x2-18x +4. Over which of these domains could you define f-1(x)? Remember that f(x) must be one-to-one (only one y-value for each x-value) over the domain where f-1(x) is defined as a function. So, in some cases you must restrict the domain of f(x) so that it's one-to-one. There might be more than one section of domain that's one-to-one. HINT: The function f(x) is one-to-one wherever it's monotonic ("monotonic" simply means increasing or decreasing over the entire interval, so the derivative does not change sign). To find these intervals, start by taking the first derivative, which is f'(x) = 3x² + 3x - 18, and setting it equal to zero. 1. (-∞, -3] II. [-3, ∞) III. [2, ∞) || ||| Either I or II Either I or III
The graph of f(x) is given above. Which of the following functions increase or decrease as f(x) does over (−∞, 3) and (3, ∞)? Select the two correct answers. g(x)=x−3 g(x)=−|x−3| g(x)=−(x−3)2 g(x)=(x−3)2 g(x)=|x−3|

Use the intermediate value theorem to show that function has a zero between the two numbers given. Then, use your calculator to approximate the zero to the nearest hundredth. P(x)=8x^4 - 8x^2 + 20x -16; 0.5 and 1 (a) evaluate the function for the lower bound, 0.5 P(0.5)= ? (b) evaluate the function for the upper bound, 1 P(1)= ? Why do P(0.5) and P(1) show that the function has a zero between 0.5 and 1? Multiple choice A. Since P(0.5) and P(1) have the same sign, there exists at least one real zero between 0.5 and 1. B. Since P(0.5) # P(1), there exists at least one real zero between 0.5 and 1 C. Since P(0.5) < P(1), there exists at least one real zero between 0.5 and 1. D. Since P(0.5) and P(1) are opposite in sign, there exists at least one real zero between 0.5 and 1.
