Question 25 refers to the following figure.
Begin skippable figure description.The figure presents a 2‑column table with 3 rows of data. The heading for the first column is “x,” and the heading for the second column is “f of x.” The 3 rows of data are as follows. Row 1: x, 0; f of x, negative 2. Row 2: x, 2; f of x, 4. Row 3: x, 6; f of x, 16. End skippable figure description.Question 25.Some values of the linear function f are shown in the preceding table. What is the value of  f of 3?
A. 6 B. 7 C. 8 D. 9 Question 26 refers to the following information.A gear ratio r:s (r to s) is the ratio of the number of teeth of two connected gears. The ratio of the number of revolutions per minute of two gear wheels is s:r (s to r). In the following diagram, Gear, A, is turned by a motor. The turning of Gear, A, causes Gears B and C to turn as well. 
Begin skippable figure description.The figure presents a diagram of 3 gears of three different radii arranged side by side such that Gear, A, is interlocked with Gear B and Gear B is interlocked with Gear C. The gears are labeled, from left to right, as follows. “Gear, A, 20 teeth,” “Gear B, 60 teeth,” and “Gear C, 10 teeth.” End skippable figure description.Question 26.If Gear, A, is rotated by the motor at a rate of 100 revolutions per minute, what is the number of revolutions per minute for Gear C? A. 50 B. 110 C. 200 D. 1,000
Question 27.In the x y‑plane, the graph of  2 x squared minus 6 x, plus 2 y squared plus 2 y, equals 45 is a circle. What is the radius of the circle?
