(a) Find the critical number(s) of s. (b) Is the graph of s increasing, decreasing, or neither, at t = Increasing Decreasing t = (c) Find the inflection point: (t, s) = (- (d) Is the graph of s concave up or concave down at t = Concave Up Concave Down 3 seconds? (circle one) Neither 3 seconds? (circle one) Neither

T4. The point (-3, 8) is on the graph of y = 2f(x + 1) - 4. What was the original point on the graph of y = f(x)? (-4, 10) (4,5) It's impossible to know without knowing the parent function (-2,6)

f(x) = x1 Choose the correct graph below with the viewing window [-10,10,-10,10], with Xscl=2 and Yscl = 2. OA. Q G The domain is (Type your answer in interval notation.) OB. I G O D. X 26 Q OU

4. Let G represent the number of gallons of gasoline left in a car’s tank after it has been driven m miles from a filling station where it was last filled. The table below gives se- lected values of these quantities:   (a)  What kind of function is G = G(m)? How can you tell? (b) Determine the slope of the line that connects the first point (40, 11) to the last point (200, 3) from the table above. Interpret what this number tells us about how this car uses gasoline. (c)  Find the y-intercept of the line that connects the first point (40, 11) to the last point (200, 3) from the table above. Interpret what this number tells us about how this car uses gasoline.
