Step-by-Step Solution

To find the axis of symmetry for the quadratic function f(x)=4x2+6 f(x) = 4x^2 + 6 , we employ the formula for the axis of symmetry of a parabola given by ax2+bx+c ax^2 + bx + c , which is x=b2a x = -\frac{b}{2a} .

Given f(x)=4x2+0x+6 f(x) = 4x^2 + 0x + 6 , we identify the coefficients from the function:

  • a=4 a = 4
  • b=0 b = 0

Substituting these values into the formula:

x=b2a=02×4=0 x = -\frac{b}{2a} = -\frac{0}{2 \times 4} = 0

Thus, the axis of symmetry for the quadratic function is x=0 x = 0 .

Therefore, the solution to the problem is x=0\mathbf{x = 0}.

Answer

x=0 x=0
