Question 2 Open the graphing tool, and select the data tab. Copy and paste your data from the table (x- and y-coordinates). Don’t include any dollar signs. Plot the data on the graph.

Under the relationship tab, use the linear, exponential, and quadratic function tools with “best fit” selected to view the regression model. Zooming in and out will help you get a better view of each fit. Observe how well each model fits the data. Rank the three function types (linear, exponential, quadratic) in order from best fit to worst fit.

Write two to three sentences justifying your reasoning for the ranking you chose in question 2.

Using the graph below, select all statements that are true. a. f(0.6)=0 b. f(-3.2)=-3 c. f(5.1)=5 d. this is the graph of the greatest integer function. e. this graph is one-to-one.

What is the length of the segment, endpoints of which are intersections of parabolas y=x^2− 11/4 x− 7/4 and y=− 7 /8 x^2+x+ 31/8 ?

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
