WebMay 25, 2024 · Maximum/minimum value Here we're dealing with looking at the vertex and seeing if it is as high as the parabola goes (i.e. maximum and is when there is a negative sign sitting in front of the (x − h)2 term) or as low as it goes (i.e. minimum and is when there is a positive sign sitting there). WebFor instance, the graph of y=f (x) y=f (x) shows that 7 7 (the y y -coordinate of the vertex) is the maximum y y -value that the function outputs. Furthermore, since the parabola opens down, every y y -value below 7 7 is also a possible output. In other words, the range of f f is all y y-values less than or equal to 7 7. This is it!
