Multiple Choice

The green line is generated by y=0.

Which equation generates the blue line?

• y=1

• y=2

• y=3

• y=4

Multiple Choice

The green parabola is generated by y=(x-2)².

Which equation generates the blue parabola?

• y=(x-1)²

• y=(x-2)²

• y=(x-3)²

• y=(x-4)²

Multiple Choice

If we have these two equations:

y=(x-4)², y=3

Then when we combine them with transitive, we get...

• (x-2)²=3

• (x-4)²=3

• (x+2)²=9

• (x+4)²=9

Multiple Choice

If we take the square root of both sides of

(x-4)²=3

We get...

• $$x-4=\pm\sqrt{3}$$

• $$x-4=\pm\sqrt{9}$$

• $$x-2=\pm\sqrt{3}$$

• $$x-2=\pm\sqrt{9}$$

Multiple Choice

If we add 4 to both sides of

$$x-4=\pm\sqrt{3}$$ , we get

• $$x=4\pm\sqrt{3}$$

• $$x=-4\pm\sqrt{3}$$

• $$x=2\pm\sqrt{3}$$

• $$x=-2\pm\sqrt{3}$$

Multiple Select

Which two expressions split from this one?

$$4\pm\sqrt{3}$$

• $$4+\sqrt{3}$$

• $$4-\sqrt{3}$$

• $$2+\sqrt{3}$$

• $$2-\sqrt{3}$$
