Question

What is the line of symmetry of graph of f(x)=(x+2)²-5

a. x=-5
b. x=-2
c. x=2
d. x=5

thank u very much❤️​

Answer 1

It is x=-5 it is right

Answer 2

The line of symmetry is like vertex but without k value.

From (h, k) which is vertex. h is basically a line of symmetry.

Therefore if vertex for the graph is (-2,-5)

The line of symmetry would be x=-2

So the answer is B.
