Question

The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the graph?

Answer 1

y would be -9 i think

so th coordinates would be (-2,-9)

Step-by-step explanation:

just plug in -2 for x and u should get -9

hoped that helped:P

Answer 2

Answer: Vertex is (-2, -9)

=======================================================

Step-by-step explanation:

The vertex of the parabola is always located on the axis of symmetry. This indicates that the x coordinate of the vertex is x = -2.

Plug x = -2 into the function to find the y coordinate of the vertex.

f(x) = x^2 + 4x - 5

f(-2) = (-2)^2 + 4(-2) - 5

f(-2) = 4 - 8 - 5

f(-2) = -9

The vertex is (-2, -9)

Side note: The equation y = x^2+4x-5 in standard form converts to the vertex form of y = (x+2)^2 - 9
