Use the parabola tool to graph the quadratic function f(x)=−12x2+7. Graph the parabola by first plotting its vertex and then plo
Fudgin [204]
First we find the vertex of parabola f(x)=-12 x^{2} +7

The vertex of parabola is ( \frac{-b}{2a},f( \frac{-b}{2a}))
Here,
b = coefficient of x term
a = coefficient of x² term

For given parabola, b = 0 , a = -12

So,
\frac{-b}{2a}= \frac{0}{-24} =0

And,

f( \frac{-b}{2a} )=f(0) = -12(0)+7=7

Thus the vertex of parabola is (0, 7)

To find another point on parabola, substitute x by 1.

f(1)=-12( 1^{2}) +7=-12+7=-5

So the second point on parabola is (1,-5)

The plot of parabola is shown in image below:
