Step-by-step solution

To solve for point C on the graph of the function f(x)=x26x+8 f(x) = x^2 - 6x + 8 , we will determine the y-intercept of the graph.

According to the properties of a quadratic function, the y-intercept is found by evaluating the function at x=0 x = 0 . This provides the point where the graph crosses the y-axis.

Substituting x=0 x = 0 in the equation:

f(0)=(0)26×0+8=8 f(0) = (0)^2 - 6 \times 0 + 8 = 8

Thus, the y-coordinate of the intercept, and point C, is 8. Hence, point C is located at (0,8) (0, 8) .

Therefore, the solution to the problem is (0,8) (0, 8) .
