Find the range of the graphed function
give brainliest

-4 ≤ y ≤ 8

Step-by-step explanation:

The range is the set of y-values for which the function is defined. When we are asked to find the range of a function (given in a graphical form), we look from which y-value (lowest) till which y-value (highest) the function is graphed for (defined for).

First, looking at the y-axis, we see that 5 bars in the coordinates is 10 units, so each bar is :

10/5 = 2 units

Now, looking at the lowest value, we see that it is 2 units from y = 0, so that is at:

y = -2 * 2 = -4

Now, looking at the highest value, we see that it is 4 units from y = 0, so that is at:

y = 4 * 2 = 8

So, the range is from y = -4 to y = 8. This can be written as:

-4 ≤ y ≤ 8
