Understand the problem

Find the corresponding algebraic representation of the drawing:

(-2,7)(-2,7)(-2,7)

2

Step-by-step solution

To determine the algebraic representation, we use the vertex form of a parabola, which is y=(xh)2+k y = (x-h)^2 + k . Here, the vertex is placed at (2,7)(-2, 7), thus plug these values into our equation: h=2 h = -2 and k=7 k = 7 .

Consequently, the equation of the parabola becomes:

y=(x+2)2+7 y = (x + 2)^2 + 7

This representation correctly describes a parabola that passes through the vertex at (2,7)(-2, 7) and opens upwards, as indicated by the absence of a negative sign or alternate coefficient in front of the square term.

Therefore, the correct choice corresponding to this problem formulation is:

y=(x+2)2+7 y = (x + 2)^2 + 7

Final Answer

y=(x+2)2+7 y=(x+2)^2+7
