Find the equation of the axis of symmetry for the parabola y = x^2 + 3x + 1 . Simplify any numbers and write them as proper fractions, improper fractions, or integers. _____

Identify Coefficients: Identify the coefficients of the quadratic equation. The quadratic equation is given by y = ax^2 + bx + c. For the parabola y = x^2 + 3x + 1, we can compare it to the standard form and identify the coefficients as follows: a = 1 (coefficient of x^2) b = 3 (coefficient of x) c = 1 (constant term)Use Axis of Symmetry Formula: Use the formula for the axis of symmetry. The axis of symmetry for a parabola given by the equation y = ax^2 + bx + c is x = -b/(2a). We will substitute the values of a and b into this formula to find the axis of symmetry.Calculate Axis of Symmetry: Calculate the axis of symmetry. Substitute a = 1 and b = 3 into the formula x = -b/(2a): x = -3/(2*1) x = -3/2 This is the equation of the axis of symmetry for the parabola.

Identify Coefficients: Identify the coefficients of the quadratic equation. $\newline$ The quadratic equation is given by $y = ax^2 + bx + c$ . For the parabola $y = x^2 + 3x + 1$ , we can compare it to the standard form and identify the coefficients as follows: $\newline$ $a = 1$ (coefficient of $x^2$ ) $\newline$ $b = 3$ (coefficient of $x$ ) $\newline$ $c = 1$ (constant term)
Use Axis of Symmetry Formula: Use the formula for the axis of symmetry. $\newline$ The axis of symmetry for a parabola given by the equation $y = ax^2 + bx + c$ is $x = -\frac{b}{2a}$ . We will substitute the values of $a$ and $b$ into this formula to find the axis of symmetry.
Calculate Axis of Symmetry: Calculate the axis of symmetry. $\newline$ Substitute $a = 1$ and $b = 3$ into the formula $x = -\frac{b}{2a}$ : $\newline$ $x = -\frac{3}{2\cdot 1}$ $\newline$ $x = -\frac{3}{2}$ $\newline$ This is the equation of the axis of symmetry for the parabola.
