Pls solve the last box I don’t understand it. Thnx :)
Pavel [41]

Answer:

(0, -3) and (2, 1)

Step-by-step explanation:

There are 5 points marked on the graph: (±2, 1), (±1, -2) and (0, -3). These are solutions to the equation describing the function:

... y = x² - 3

Apparently, you are being asked to report the coordinates of any two of these points.

<em>Comment on the problem</em>

The wording "solutions to the function" is a bit odd. An equation has solutions—values of the variables that make it be true. A function is a relationship between values, a definition. There is nothing  to solve.

In the above we have assumed the intent is to find (x, y) pairs that match the function definition. Sometimes, we're interested in values of x that make y be zero. (x, y) = (±√3, 0) It isn't obvious what the intent of this question is.
