Q1 Graph the function and identify the domain and range y=-2x2

1 answer

To graph the function y = -2x^2, we can start by plotting a few points and then connecting them to form a curve.

Some points to plot are:
(-2, -8)
(-1, -2)
(0, 0)
(1, -2)
(2, -8)

Now, we connect these points to form a downward facing parabola.

The domain of the function y = -2x^2 is all real numbers, since the function is defined for all values of x.

The range of the function y = -2x^2 is all real numbers less than or equal to 0, since the function's maximum value is 0 and it decreases for all values of x.
