Write the quadratic function in standard form fx x2 8x 13

Write the quadratic function in standard form. f(x) = x2 + 8x + 13

What is the vertex, axis of symmetry, x-intercept, and y intercept. I really need help with the step with this please, I am so confussed.

f(x\\) = x^2 +8x +13

Vetrex ( h, k)

h = -b/2a = -8/2*1 = -4

k = (-4)^2 -4*4 +13 = 16 -32 +13 = -3

Vertex ( -4, -3)

X intercept: f(x) =0 ;x2 + 8x + 13 =0

Solve the quadratice equation

x = -2.26; x = - 5.7 are x intercept

Y interecpt : Pllig x=0 ; y = 13 y intercept
