Question

What are the coordinates of the vertex for f(x) = x2 + 4x + 10?

(−2, 2)

(2, 2)

(−2, 6)

(2, 6)

Answer 1

Do you mean \[x^2+4x+10\] ?

Answer 2

yes

Answer 3

The answer would be: C, (-2,6)
I just put it in my graphing calculator and it shows the vertex

Answer 4

the x coordinate for the vertex is -b/2a given the eqn in the form ax^2 + bx + c the y value is f(x)

Answer 5

-b/2a = -(4)/2*1 = -2
f(-2) = (-2)^2 + 4(-2) + 10 = 4 - 8 + 10 = 6
coordinates of the vertex using my natural calculator (-2, 6) as above
