2 3. For the function f(x) = 5(x − 15)2 − 100 , explain how you can identify each of the following
without graphing.
a) the coordinates of the vertex b) the equation of the axis of symmetry c) the direction of opening d) the maximum or minimum value e) the domain and range f) the number of xintercepts 4. Without graphing, identify the location of the vertex and the axis of symmetry, the direction of
opening and the maximum or minimum value, the domain and range, and the number of
xintercepts.
a) y = −4x2 + 14 b) y = (x + 18)2 − 8 d) y = − 1 (x + 4)2 − 36
