Unformatted text preview: W (2) and W ′ (2)? d) Explain the relationships between the numerical answers in a) and c). 4. It is true that Q ( x ) = x 5 + x 3 + x is a onetoone function whose domain and range are all real numbers? a) Graph Q ( x ) on the interval2 ≤ x ≤ 2. b) Suppose that R is the function inverse to Q . There is no simple algebraic way to compute values of R . Compute R (3), R ′ (3) and R ′′ (3). Hint. Q ( R ( x )) = x and R ( Q ( x )) = x . Find an input to Q which will “output” 3. Then di²erentiate one of the equations (maybe more than once)....
