Evaluating Functions/Multiple Representations Practice

Find the Range given the Domain in each situation on the left. Be sure to show work.

1a) y = 3x – 2 Domain: {-1, 2, 4} Range: ____________________________

1b) Now rewrite this function as a set of ordered pairs. { ________________________________________}

2a) y = 2x2 Domain: {-3, 0, 4} Range: ___________________

2b) Now rewrite this function as a mapping.

3a) f(x) = 2x2 + 5 Domain: {-2, 0, 1, 6} Range: _________________

3b) Now rewrite this function as a table of values.

x y

4a) g(x) = -4 – 2x Domain: {-3, -2, -1, 0, 1} Range: ___________________________

4b) Now represent this function as a discrete graph.
