Explanation Given: The path of the earth around the sun is an ellipse with the sun at one focus. The ellipse has major axis of length 186 , 000 , 000 mi and eccentricity 0.017 . Approach: e = c a . Here, e is eccentricity, c is focal length, and a is half of the length of the major axis. The shortest distance between focus and the ellipse is a − c . Calculation: Length of major axis, 2 a = 186 , 000 , 000 , so a = 93 , 000 , 000 . Eccentricity, e = 0.017 . c = a e = 93 , 000 , 000 × 0 To determine (b) To find: The distance between the earth and the sun when the earth is closest to the sun.

Name: Tay Jones Level Two Date: Algebra 3 Unit 3: Functions and Equations Practice Assessment Class: #7-OneNote 1. The function f(x) = x² is transformed in the following functions. List the vertex for each function, circle whether the function opens up or down, and why. All three parts must be correct to receive Level 2 points. You can receive points for a, b, and c. a) g(x) = -2(x+5)² Vertex: Opens Up Opens Down Why? ais negative -2 Vertex: b) g(x) = (x + 2)² - 3 c) g(x) = -4(x + 2)² + 2 Opens Up Opens Down Vertex: Opens Up Opens Down Why? 4 Ca is negative) Why? his positive 2. The graph of the function f(x) is shown below. Find the domain, range, and end behavior. Then list the values of x for which the function values are increasing and decreasing. f(x) Domain: End Behavior: As x → ∞o, f(x) -> -6 As x, f(x) -> Range: Where is it Increasing? (002] Where is it Decreasing? (1,00)
