To find the point symmetric to the y-intercept, we need to find the y-coordinate of the y-intercept first.
The y-intercept is the point where the graph of the function intersects the y-axis. It occurs when x = 0.
So, plugging in x = 0 into the equation f(x) = -x^2 + 5x - 6, we get:
f(0) = -(0)^2 + 5(0) - 6 = -6
Therefore, the y-intercept is (0, -6).
To find the point symmetric to the y-intercept, we need to find the x-coordinate first. The x-coordinate of the point symmetric to the y-intercept is the same as the x-coordinate of the y-intercept, but with the opposite sign.
So, the x-coordinate of the point symmetric to the y-intercept is 0.
Now, to find the y-coordinate, we need to evaluate the function for x = 0.
f(0) = -0^2 + 5(0) - 6 = -6
Therefore, the point symmetric to the y-intercept is (0, -6).
None of the given answer choices matches the point (0, -6), so the correct answer cannot be determined from the given choices.
