Question

what is the y-intercept? please show the steps

Answer 1

Hi Yittel,

The y-intercept describes the location when the function touches the y-axis. We know that on the y-axis, x is equal to zero.

Therefore, we have to substitute zero for x in f(x).

f(0) = (0-3)(0-1)(0+2)

= (-3)(-1)(2)

= 6

*The negatives make a positive

Therefore, the coordinate of the y-intercept would be (0,6)

Hope this helps!

Answer 2

So, remember that x = 0 all along the y-axis, right?

f(0) = (0 - 3)(0 - 1)(0 + 2) = -3(-1)(2) = 6
