Question

How to find the y-intercept given `f(x) = -3x^2 + 6x -2`?

Answer 1

`"y-intercept "=-2`

Explanation:

`"The graph crosses the y-axis when x = 0"`

`"substituting x = 0 into the equation gives the y-intercept"`

`rArrf(0)=0+0-2=-2larrcolor(red)"y-intercept"`
graph{(y+3x^2-6x+2)((x-0)^2+(y+2)^2-0.04)=0 [-10, 10, -5, 5]}
