What is the range of the function graphed on the grid? { x │ x = -2, 2, 4} {y│-3 ≤ y ≤ 4} {y│ y = -3, 0, 4} { x │-2 ≤ x ≤ 4}

Neporo4naja [7]

Answer:

The image is sideways.

But if your graph is like on the image, then the answer is: {y│-3 ≤ y ≤ 4}

Range is the set of y values

Least function value is -3 and greatest is 4
