Step-by-step explanation:
If 7 × 2 = 14, then 14 + 14 = 28. So, 7 times 4 equals to 28. You can add 14 + 14 or multiply 7 and 4 to get your answer.
If the rate of change (ROC) of the function is quadratic, then the function type is cubic
<h3>What is rate of change?</h3>
The rate of change of a function is the rate at which the output values change over the input value
The rate of change of a function is one degree less than the actual function
This means that, a cubic function will have a quadratic rate of change
Hence, the correct option is (d)
