To find the vertex of the quadratic function \( f(x) = 2x^2 - 12x + 13 \), we can use the vertex formula \( x = -\frac{b}{2a} \). Here, \( a = 2 \) and \( b = -12 \). Calculating the x-coordinate of the vertex: \[ x = -\frac{-12}{2 \cdot 2} = \frac{12}{4} = 3 \] Now we substitute \( x = 3 \) back into the function to find the y-coordinate: \[ f(3) = 2(3)^2 - 12(3) + 13 = 18 - 36 + 13 = -5 \] Therefore, the vertex of the quadratic function is \( (3, -5) \).
