In the diagram below AC and DE are parallel?

Given f(t) = 282 - 53 +1, determine the function value f(2). do not include f(z) = in your answer

Sketch one cycle if the cosine function y=2cos2theta

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
