Answer:
a. x = 3 and x = 6
Explanation:
To find the zeros of this function, you have to look at when the function intersects the x-axis.
In this case, the parabula is intersecting the x-axis at x = 3 and x = 6. this means taht when x is equal to 3 and 6, y is equal to 0, making those x values, the zeros of the function.
Hope this helps! :)
