Increasing and decreasing intervals

A coordinate plane. The x-axis scales by one, and the y-axis scales by zero point five. The graph of y equals h of x is a continuous curve. From left to right, it passes through the point negative four, zero point seven-five and the x-intercept negative three, zero. It continues to decrease until the local minimum at negative one point five, negative one. Then it increases through the point negative one, negative zero point seven, five, the origin, and the point one, zero point seven-five. It increases until the local maximum at one point five, one. Then it decreases through the x-intercept three, zero and the point four, zero point seven-five. All values are estimated.
