Question
 Use the graph to determine the following.     a. the​ function's domain b. the​ function's range c. the​ x-intercepts, if any d. the​ y-intercept, if any e. the function​ values, f(−2) and f(2).   Assume that the graph of the function continues its trend beyond the displayed coordinate grid. -10-5510-10-5510xy         A coordinate system has a horizontal x-axis labeled from negative 10 to 10 in increments of 1 and a vertical y-axis labeled from negative 10 to 10 in increments of 1. A V-shaped graph that opens upward has vertex (0, 2) and passes through the points (negative 2, 4), (2, 4), and (3, 5).
a. What is the​ function's domain?
