What is the axis of symmetry and vertex for the function [tex]f(x)=3(x-2)^2+4[/tex]?

- Axis of symmetry: [tex]x = \square[/tex]
- Vertex: [tex](\square, \square)[/tex]



Answer :

To find the axis of symmetry and the vertex for the function [tex]\( f(x) = 3(x - 2)^2 + 4 \)[/tex], let's analyze the function step-by-step.

1. Identify the form of the quadratic function:
The given function is in the vertex form of a quadratic equation, which is
[tex]\[ f(x) = a(x - h)^2 + k \][/tex]
In this form, [tex]\((h, k)\)[/tex] represents the vertex of the parabola and [tex]\(x = h\)[/tex] is the axis of symmetry.

2. Extract the values of [tex]\(h\)[/tex] and [tex]\(k\)[/tex]:
By comparing the given function [tex]\( f(x) = 3(x - 2)^2 + 4 \)[/tex] with the standard vertex form [tex]\( f(x) = a(x - h)^2 + k \)[/tex], we can identify the values:
[tex]\[ h = 2 \][/tex]
[tex]\[ k = 4 \][/tex]

3. Determine the axis of symmetry:
The axis of symmetry for the parabola is a vertical line that passes through the vertex. Since [tex]\( h = 2 \)[/tex], the axis of symmetry is:
[tex]\[ x = 2 \][/tex]

4. Determine the vertex:
The vertex of the parabola is the point [tex]\((h, k)\)[/tex]. Using the identified values:
[tex]\[ h = 2 \][/tex]
[tex]\[ k = 4 \][/tex]
Thus, the vertex is:
[tex]\[ (2, 4) \][/tex]

Therefore, the axis of symmetry is [tex]\(x = 2\)[/tex] and the vertex is [tex]\((2, 4)\)[/tex].

[tex]\[ \text{Axis of Symmetry: } x = 2 \][/tex]
[tex]\[ \text{Vertex: } (2, 4) \][/tex]
