Find the vertex and axis of symmetry of

f (x) = ( x - 1)² + 7

The vertex is ( , ). The axis of symmetry is x =

1 answer

The function \( f(x) = (x - 1)^2 + 7 \) is in vertex form, which is given by \( f(x) = a(x - h)^2 + k \), where \( (h, k) \) is the vertex of the parabola.

From the given function:

  • \( h = 1 \)
  • \( k = 7 \)

Thus, the vertex is \( (1, 7) \).

The axis of symmetry for a parabola in vertex form is given by the line \( x = h \). Therefore, the axis of symmetry here is:

\[ x = 1 \]

In conclusion, we have:

  • The vertex is \( (1, 7) \).
  • The axis of symmetry is \( x = 1 \).
