Convert the following function into intercept form:
 f(x)=x2+4x12f\left(x\right)=x^2+4x-12  

 f(x)=(x+2)(x6)f\left(x\right)=\left(x+2\right)\left(x-6\right)  

 f(x)=(x+2)216f\left(x\right)=\left(x+2\right)^2-16  

 f(x)=(x2)(x+6)f\left(x\right)=\left(x-2\right)\left(x+6\right)  

 f(x)=(x2)216f\left(x\right)=\left(x-2\right)^2-16
