Question

What is the “range” of this function f(x)=x^2 -2

Answer 1

`R=(-2,\infty)`

Step-by-step explanation:

We need to plot the function to have an understanding of the range.

The range of a function is the values that f(x) can take (the values in the y-axis).

The graph is the following:

We can see that in the y-axis (the vertical axis) the function takes values from -2 and upwards.

The red line represents the range, wich is:

`R=(-2,\infty)`
