The options that are correct regarding graph of f(x) is:
The function in vertex form is The y-intercept of the function is (0, 5). The function crosses the x-axis twice.Step-by-step explanation:The function f(x) is given by:
We know that if the equation of parabola is written in general form as:
Then the vertex of parabola is: (h,k)
Also, the x-coordinate of vertex is the equation of the axis of symmetry of parabola.
Hence, on converting the equation to general form we get:Hence, the vertex of parabola is at (4,-11)and the axis of symmetry of parabola is: x=4Also, the y-intercept is the point where x=0Hence, when x=0 we get: f(x)=5Hence, y-intercept is: (0,5)
Also, by the graph we see that the graph of the function crosses the x-axis twice ( at x=0.683 and at x=7.317 )Ответ:
