Question

How can you find the range of a quadratic function if the domain is all real numbers and we are given a table of values?

Answer 1

Answer:

(3)

$Range=[6,\infty)$

Explanation:

Given:

To find:

The range of the function

From the given table of values, we can go ahead and graph the function as seen below;

Recall that the range of a function is a set of possible dependent or output values that are on the y-xis. It includes y-values from the bottom to the top of the graph.

Looking at the above graph of the function, we can see that the graph starts from the bottom, y = 6, along the y-axis, and goes all the way up to infinity, so the range of the function is [6, infinity);

$Range=[6,\infty)$
