Let A(a) = |" f(t)dt where f is the function given by the graph below. 4- -2 -3 -4 А(5)

to succeed later in iFe, you need to 3. Given f(x)=1/3x-8, answer the following questions. a What would f(x) change to if the function is reflected across the x-axis? 100 b. What would the new equation (in a) change to if it is translated up 17 units? c. Graph both of these functions on the grid below. For what deme the Func Continue on the following page.

Near what points can the equation 2x? + xy + y? = 7 not be solved for y as a function of x? %3D O A. (2, -1) and (-2, 1) О В.(2, -1), (-2, 1), and (0, 0) о С.(2, 1), (-2, -1), (2, -1), and (-2, 1) O D. (2, 1) and (-2, -1) O E. (2, 1) and (2, -1)
