Answer:
y = 6
y = 0
y = 0
Step-by-step explanation:
[tex]y=\frac{1}{2}x² -2x[/tex]
When, x = -2
[tex]y=\frac{1}{2}\times (-2)^2-2\times(-2)\\\Rightarrow y=\frac{1}{2}4+4\\\Rightarrow y=2+4\\\Rightarrow y=6[/tex]
y = 6
When, x = 0
[tex]y=\frac{1}{2}\times (0)^2-2\times(0)\\\Rightarrow y=0+0\\\Rightarrow y=0[/tex]
y = 0
When, x = 4
[tex]y=\frac{1}{2}\times (4)^2-2\times(4)\\\Rightarrow y=\frac{1}{2}16-8\\\Rightarrow y=8-8\\\Rightarrow y=0[/tex]
y = 0
