State the vertex, axis of symmetry, and domain & range for each quadratic. f ( x ) = ( x + 1 4 ) 2 + 3 f\left(x\right)=\left(x+\frac14\right)^2+3

this problem, we need to find the vertex, axis of symmetry, and domain and range for this quadratic. X plus one fourth, all squared, plus three. So let's start with our vertex. Here, we have two shifts. We have a horizontal shift and a vertical shift. We're gonna rewrite this to look more like our form of x minus h. So we'll rewrite it as x minus negative one fourth, which makes it easy to see that we have a shift to the left of one fourth. We also have a shift upwards of three, which means our new vertex is going to be at negative one fourth, positive three. Next, for our axis of symmetry, it always runs through the vertex and shares its value with the x value. So it's going to be the vertical line, x equals negative one fourth. Lastly, for our domain and range, we know that the domain is always the same from negative infinity to positive infinity, but our range depends on the vertex. Our vertex y value is at three, And since this quadratic is positive in front, that means that it's opening upward, so that our vertex is then a low point for our graph. So that means the range of this parabola is going to be from three to positive infinity.

Verified step by step guidance

Identify the quadratic function given in vertex form: $f\left(x\right)=\left(x+\frac{1}{4}\right)^2+3$.

Recall that the vertex form of a quadratic is $f\left(x\right) = a\left(x-h\right)^2 + k$, where the vertex is at $(h, k)$.

From the given function, rewrite $x + \frac{1}{4}$ as $x - \left(-\frac{1}{4}\right)$, so the vertex is at $\left(-\frac{1}{4}, 3\right)$.

The axis of symmetry is the vertical line that passes through the vertex, so it is $x = -\frac{1}{4}$.

The domain of any quadratic function is all real numbers, so the domain is $\left(-\infty, \infty\right)$. Since the parabola opens upwards (coefficient of squared term is positive), the range starts at the vertex's y-value and goes to infinity: $\left[3, \infty\right)$.
