Question

Find the x-and y-intercepts of the parabola y=−x

2
−16x−64. Enter each intercept as an ordered pair (x,y). Use a comma to separate the ordered pairs of multiple intercepts. You may enter an exact answer or round to 2 decimal places. If there are no solutions or no real solutions for an intercept enter ∅ Provide your answer below:

Answer 1

Explanation:

Factor to (-x -8)(x-8) to see the x-axis intercept (there is only one) is (-8,0)

then the y-axis intercept occurs when x = 0 <====sub that into equation to find (0, −64) for y-axis intercept
