Graph g(x)=3x^2−12x−3 .

use the parabola tool then choose the vertex followed by one point on the parabola.

answer:

step-by-step explanation:

[o

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

so mark-up is 0.4 multiplied by 180 = 72
