Question

What is the lowest value of the range of the function shown on the graph! Please help asap

Answer 1

The range of a function is the set of the all values taken by the function, for all possible inputs.

When you watch this from a graphical point of view, the range is the portion of the y axis that the graph spans.

In this case, you can see that the lowest point reached by the function (its minimum) is $(3,-2)$. You can also see that the function is unbounded upwards.

So, the range is $[2,\infty)$, and the lowest value is thus 2.
