The graph of the quadratic function is on the image at the end.
How to graph the quadratic function?
Here we want to graph the quadratic function:
f(x) = -x² - 2
To do so, we can complete the table of values by evaluating the function.
if x = ±2 then:
f(±2) = -(±2)² - 2 = -4 - 2 = -6
if x = ±1
f(±1) = -(±1)² - 2 = -1 - 2 = -3
if x = 0
f(0) = -(0)² - 2 = - 2 = -2
Then we have the points:
(-2, -6), (-1, -3), (0, -2), (1, -3), (2, -6)
Now just graph these points and connect them with a curve. The graph of the parabola is below.
