Please answer!!

Use the parabola tool to graph the quadratic function.

f(x)=3x^2+6x−24

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

Answer:

See below

Explanation:


f(x)=3x^2+6x-24\\\\f(x)=3(x^2+2x-8)\\\\f(x)+3(9)=3(x^2+2x-8+9)\\\\f(x)+27=3(x^2+2x+1)\\\\f(x)=3(x+1)^2-27

Here, we can see that the vertex of the parabola is
(-1,-27) when we compare to the equation
y=(x-h)^2+k with vertex
(h,k).

A second point you could plot is the y-intercept, when
x=0:


f(0)=3(0+1)^2-27\\\\f(0)=3-27\\\\f(0)=-24

So, your y-intercept is
(0,-24).
