Answer:
y = 2 - x^2
Substitute the different values of x to find y.
Input x -2 -1 0 1 2
Output y -2 1 2 1 -2
Graph this.

Pink - 1,1
Green - 2,-2
Cos(pi) = -1
You should have this memorized along with other values such as
sin(0) = 0
cos(0) = 1
sin(pi/2) = 1
cos(pi/2) = 0
sin(pi) = 0
cos(pi) = -1
sin(3pi/2) = -1
cos(3pi/2) = 0
and remember that tan = sin/cos
The diagram is shown in the picture. The real numbers are divided into rational numbers and irrational numbers. Example of a rational number is any fraction like 1/2, while an irrational number is one that cannot be expressed as a fraction like π. Then, integers are also part of the rational numbers which include positive and negative whole number like -5, and +4. Whole numbers are positive numbers from 0 to whatever number. Lastly, the natural numbers are whole numbers with the exception of zero. So, these are numbers from 1 to infinity.
