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?

(-9, - 2)

(-17, - 2)

(-2, - 17)

(-2, - 9)

Easy

ok so the x value of the axis of symmetry is also the x value for the vertex

to get the y value, plug the x value into the equation and evaluate

x=-2

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

f (-2) = 4-8-5

f (-2) = - 9

yvalue is - 9

coordinates are in (x, y) form

x=-2

y=-9

(-2,-9)

last one is answer
