Question 3

Graph the equation. 
A) 
B) 
C) 
D) 
E)

Accepted Answer

The given equation does not make sense as it is a random string of characters and numbers. Therefore, it cannot be graphed.

Question 4

Graph the equation. Begin by completing the square on the first two terms. 
A) 
B) 
C) 
D) 
E)

Accepted Answer

Completing the square on the first two terms gives us (x+5)²-25. Therefore, the equation is y = (x+5)²-25. This is a parabola with vertex at (-5,-25) and it opens upwards since the coefficient of the squared term is positive.
