Question

State the y-coordinate of the y-intercept for the function below of x^3-9x

Answer 1

`y = x^(3) - 9x`

`y = 0^(3) - 9(0)`

`y = 0`

Answer 2

The y coordinate of the y-intercept is 0.

Explanation:

Consider the provided function.

`y=x^3-9x`

We need to find y coordinate of y intercept.

y intercepts are the point where the x value is 0 or the line cuts the y axis.

To find the y coordinates of y intercept, substitute x=0 in the provided equation.

`y=(0)^3-9(0)`

`y=0`

Therefore, the coordinates are (0,0)

Hence, the y coordinate of the y-intercept is 0
