Use the parabola tool to graph the quadratic function f(x)=−x2+4.


Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.


What are the two points I need to graph? (x and y)

Step-by-step explanation:

Move it it up 4 and then find your x intercepts.

Find the x intercepts.

[tex]-x^2 + 4 = 0[/tex]

Move the 4 over to the right

[tex]-x^2 = -4[/tex]

Divide out the -

[tex]\frac{-x^2}{-} = \frac{-4}{-}[/tex]

[tex]x^2 = 4[/tex]

Take the square root of each side

[tex]\sqrt{x^2} = \pm \sqrt{4}[/tex]

[tex]x = \pm \sqrt 2[/tex]

Our x intercepts are at (-2,0) (2,0)
