Use the cubic model y = 10x3 − 12x to estimate the value of y when x = 3. a.) 234 b.) 270 c.) 306 d.) 36

To solve this problem you must apply the proccedure shown below:

1. You have the following function given in the problem above:

2. To estimate the value of when , you only need to substitute this value of into the function, as following:

Therefore, the answer is: A) 234
