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.
Answer:
You find percent of change
by finding the differences between the numbers given
and by setting up a fraction to find the change because percentages deals with fractions
Then you simplify ur fraction by multiplying by 100
Step-by-step explanation:
e.g
find the percent of change from 20 to 80
find their differences
80-20= 60
set up a fraction
60/20
simplify your fraction by multiplying over 100
60/20*100
3*100=300%. answer
Answer:
Complementary angles are those that sum up to 90o.Vertical angles have equal measures. Therefore, if vertical angles measure 45o each, they are complementary.
Explanation: Here how it might look if angles ∠1 and ∠3 are measured at 45o.
Answer:
6 vertices and 5 faces
Step-by-step explanation:
The faces are correct as there are 3 rectangles and 2 triangles.
So a total of 5 faces
There are 6 corners/vertices so the answer is 6 vertices
