The function g is given in three equivalent forms. Which form most quickly reveals the zeros (or "roots") of the function?

g (x) = 3 (x+1) ^2-12

g (x) = 3 (x+3) (x-1)

g (x) = 3x^2+6x-9

g (x) = 3x²+6x-9

Step-by-step explanation:

In order to be able to determine the zero of a function, the function must be in its quadratic format in order for the function to quickly reveal its zeros. The function in question must be written in its standard format as shown;

ax²+bx+c = 0 (quadratic standard)

According to the given function, the only function written in its standard form is g (x) = 3x²+6x-9 where a = 3, b = 6 and c = - 9 therefore only this form most quickly reveals the zeros (or "roots") of the function.
