Question

please help
find the vertex and the equation of the axis of symmetry. graph the function
f(x)=(x+7)^2

Answer 1

ok... so the vertex form of a parabola is

\[y = (x - h)^2 + k\]

which will have a vertex at (h, k)

in your question k = 0

you just need to find h...

Answer 2

the axis of symmetry will be x = h

Answer 3

i dont understand how to find either :(

Answer 4

y=(x+7)^2

standard form is
y=(x-a)^2+b
where a and b are the coordinates for vortex.
the axis of symmetry is alwasy the linear variable (for parabola)

here linear variable is y .
