Explanation:
#"choose 3 values for x and evaluate for y"#
#"the values of x can only be positive"#
#x=0toy=0rArr(0,0)larrcolor(red)" one point"#
#x=1toy=-9sqrt1rArr(1,-9)larrcolor(red)" second point"#
#x=4toy=-9sqrt4rArr(4,-18)larrcolor(red)" third point"#
#"plot these points and draw a smooth curve through them"#
graph{-9sqrtx [-50.63, 50.6, -25.3, 25.34]}
