Question

Determine whether the following statement is true or false. The graph of f(x)=(x+7)2+4 has its vertex at ​(7​,4​).

Answer 1

False.

The vertex is at (-7, 4).

Explanation:

f(x) = (x + 7)^2 + 4

The minimum value of (x + 7)^2 = 0 (as it's a perfect square) , so minimum of f(x) is 4 when x = -7.
