Question

use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following equation. y=x^2+x+6

Answer 1

(-1/2, 23/4)

Explanation:

Vertex of graph: -b/2a

b=1

a=1

Therefore, -1/2 is your x-value

Solve for y: y=1/4-1/2+6

y=5 3/4 or 23/4

Therefore your vertex is: (-1/2, 23/4)
