9. While standing on a 192 foot cliff, Anna throws a rock into the air and lets it fall to the bottom of the cliff. The height of the rock after x seconds can be modeled by h(x) = -16x2 + 32x + 192. Determine the time
interval over which the height of the rock will be at least 192 feet.

Your answer should be “b” i truly hope i could ! good luck (:

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
