what must be true about the signs of h and k?

ANSWER:
h must be negative and k must be positive
STEP-BY-STEP EXPLANATION:
We can determine the signs of h and k, knowing that for the graph to rise, the value of k must be positive, because of adding to the function. Therefore k has a positive sign
Now, for the graph to move to the left, it must also be added to the x within the absolute value.
Since there is a minus sign before h, for the result to be positive, h must be negative.
