A coordinate system has a horizontal x-axis labeled from negative 5 to 5 in increments of 1 and a vertical y-axis labeled from negative 5 to 5 in increments 1. A parabola that opens upward has vertex (0, negative 2) and passes through the approximate points (negative 1, negative 1.5) and (1, negative 1.5).

a. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A.

(Type your answer in interval notation. Use a comma to separate answers as needed.)

B.

There is no interval on which the function is increasing
