Sketch the graph of a function f(x) that satisfies the following criteria. (You do not need to define the function algebraically.)
• Defined and continuous on the interval (-5,5).
• f'(2) does not exist at 2 = 0
f(2+ h) – f(2)
• lim
< 0
h
• The slope tangent to the graph of f(x) at x = 3 is zero
• The rate of change of f(x) when x = -1 is positive
h0

Statements reasons 1. ab ≅ cd; ad ≅ bc 1. given 2. ac ≅ ac 2. reflexive property 3. △adc ≅ △cba 3. ? 4. ∠dac ≅ ∠bca; ∠acd ≅ ∠cab 4. cpctc 5. ∠dac and ∠bca are alt. int. ∠s; ∠acd and ∠cab are alt. int. ∠s 5. definition of alternate interior angles 6. ab ∥ cd; ad ∥ bc 6. converse of the alternate interior angles theorem 7. abcd is a parallelogram 7. definition of parallelogram what is the missing reason in step 3?
