Im so stumped. will give brainliest! find the x-intercepts of the parabola with vertex (1, -9) and y intercept at (0, -6). a. (-1, 0), (3, 0) b. (-0.73, 0), (2.73, 0) c. (-1.48, 0), (2.48, 0) d. (-4.67, 0), (1.67, 0)

and

Step-by-step explanation:

We have been given the parabola with vertex (1, -9) and y intercept at (0, -6).

Now we need to find the x-intercepts of that parabola. So first we begin by finding the equation of parabola using vertex formula:

Vertex for this formula is given by (h,k)

Compare that with given vertex (1,-9), we get: h=1, k=-9

So plug these into vertex formula:

...(i)

Plug given point (0, -6). into (i)

Plug a=3 into (i)

Now to find x-intercept, we just plug y=0 and solve for x

Hence final answer are
