The given quadratic function in vertex form is:
\[
f(x) = 3(x + 7)^2 - 2
\]
In the vertex form of a quadratic function, which is expressed as:
\[
f(x) = a(x - h)^2 + k
\]
the vertex of the parabola is at the point \((h, k)\), where \(a\) is a coefficient that determines the direction and the width of the parabola.
From your function:
- \(a = 3\): This means the parabola opens upwards (since \(a > 0\)) and is vertically stretched by a factor of 3.
- \(h = -7\): This is derived from \((x + 7)\) (which is the same as \((x - (-7))\)).
- \(k = -2\): This is the constant term outside the squared expression.
Thus, the vertex of the parabola is at the point:
\[
(-7, -2)
\]
The parabola opens upwards because \(a\) is positive. If you have any further questions about this quadratic function or need additional information, feel free to ask!
