Get max or min value

Question

How can I get the max or min value of one image? I don't know what's the function is in GEE. I have to use this for vegetation coverage For example: [1,2,3, 4,5,6, 7,8,9] max:9;min:1

Are you looking for something like this?

var geometry = ee.Geometry.Polygon(
    [[[-121.52324218749999, 37.901687004454395],
      [-121.46831054687499, 37.42335315973017],
      [-120.86406249999999, 37.46696534545472],
      [-120.89702148437499, 37.98832531444019]]]);

var modis = ee.ImageCollection("MODIS/MCD43A4_NDVI")
var modis_filtered = modis.filterDate("2010-01-01","2010-04-01").median().clip(geometry)

print(modis_filtered.reduceRegion({
      reducer: ee.Reducer.min(),
      geometry: geometry,
      scale : 250
      }))
