3. Here are graphs of two functions F and A. VW
Which statements are true of the function
8 given by g(x) = A(x) - F(x)? Select all
that apply
A. The x-intercepts are at x = 2 and x = -1.
B. The x-intercepts are at x = -2 and x = 1.
C. The y-intercept is at (0,-2).
D. The y-intercept is at (0,2).
E. When x > 1, the values of g are negative.
F. When x < -2, the values of g are positive.
4. The function H gives the height, above the ground, of a point on a spinning wheel.
The function A gives the height of a point on a different spinning wheel and is
defined by A(t) = 1.2H(3t). Here, t is time in seconds since the wheels started
moving. How does the spinning wheel modeled by function A compare to the wheel
for H? Explain how you know.
