Explanation:
"The graph crosses the y-axis when x = 0"The graph crosses the y-axis when x = 0
"substituting x = 0 into the equation gives the y-intercept"substituting x = 0 into the equation gives the y-intercept
rArrf(0)=0+0-2=-2larrcolor(red)"y-intercept"⇒f(0)=0+0−2=−2←y-intercept
graph{(y+3x^2-6x+2)((x-0)^2+(y+2)^2-0.04)=0 [-10, 10, -5, 5]}
