Question

Determine whether the following statement is true or false.

The graph of f(x) = (x + 2)2 + 4 has its vertex at (2,4).
Choose the correct answer below.
O True
0 False

Answer 1

Explanation:

No it doesn't. When you get stuck on a question like this one, you should go to Desmos and graph the equation. I've done that for you.

Correctly stated the equation should read f(x) = (x + 2)^2 + 4

As you can see from the graph the vertex is at -2,4. To find the x value of the vertex, create a small equation

x + 2 = 0

x = - 2

That will turn what is inside the brackets into 0. The value for x is always what will turn (x + a) to zero.
