    Answer:

    x=4

    Step-by-step explanation:

    We have the quadratic function:

    \displaystyle y=0.3(x-4)^2-2.5

    And we want to determine its axis of symmetry.

    Notice that this is in vertex form:

    y=a(x-h)^2+k

    Where (h, k) is the vertex of the parabola.

    From our function, we can see that h = 4 and k = -2.5. Hence, our vertex is the point (4, -2.5).

    The axis of symmetry is equivalent to the x-coordinate of the vertex.

    The x-coordinate of the vertex is 4.

    Therefore, the axis of symmetry is x = 4.
