find the x intercept

Question

what is the x int in y=x³+3 ?? pls help 

Answer 1

y = x³ + 3

 

y = 0 at the x-intercept because it is a point on the x-axis where the y-coordinate is zero for all points

 

x³ + 3 = 0

x³ = -3

³√-3

Answer 2

An x-intercept is a point on the graph where y is zero.

 

So, y = 3X + 3

let y = 0

0 = 3X + 3

0 -3 = 3X + 3 - 3

-3 = 3X

-3/3 = 3X/3

-1 = X

 

The x intercept is -1
