? + 3
? = 7
Step-by-step explanation:
3 times 7 is 21 -11 is 10
7+3 is 10
Both equations has to make 10 so it is the answer of 7
Hope this helps :)
The differences between f(x) values are 3, 6, 9, 12. The differences between those are constant: 3. When "second differences" (for uniformly spaced x values) are constant, the function is quadratic.
_____
The degree of the function is equal to the level of differences that are constant. Linear (1st-degree) functions have 1st differences that are constant; cubic (3rd-degree) functions have 3rd differences that are constant.
If each level of differences increases in the same way, the function is exponential.
