Question

what is this answer and please show me how you got it so I can know how you got it.y= 3
`√(x + 4) -6` please hurry also :0 giving 35 points to those who answer first

Answer 1

X=2


To find -intercept/zero, substitute y=0


Divide both sides of the equation by 3

The only way a root could be 0 is when the radicand equals 0

Calculate the difference
And you should get x=2
