The y-coordinate of the vertex of f(x)- x+4x+ 7 is f(2). Select the correct choice below and fill in the answer box to complete your choice. A. O B. C. D. The statement is true because the x-intercept of the parabola is The statement is true because the x-coordinate of the vertex is The statement is false because the y-coordinate of the vertex is The statement is false because the y-coordinate of the vertex is f

Explanation / Answer

For a parabola ax2 + bx + c the vertex is -b/2a

Here, a = -1, b= 4

Hence, x = -4/2(-1) = 2

Therefore, the y coordinate of vertex = f(2)

Hence, Option B. Blank = 2
