Where can the prpendicular bisectors of an acute triangle intersect? i inside the triangle ii on the triangle iii outside the triangle a. i only b. iii only c. i or iii only d. i, ii, or iii only

The meeting point of the 3 perpendicular bisectors of a triangle's sides is called the circumcenter.
The circumcenter of an acute triangle is always inside the triangle.
so the answer is "a"

When a number is added to or subtracted from a function it moves it vertically up or down.

G(x) is obtained by subtracting 3 from F(x). This means G(x) is obtained by vertical translation of F(x). Since 3 is subtracted from F(x), the vertical translation is downwards.

So, we can say: G(x) is obtained by moving F(x) 3 units vertically down.

Therefore, the correct answer is option D
