A is the right answer i think
X 0 1 2 ...
y -2 -9 -16...
(y) decreases by 7/<span> (x) increases by 1, so slope =-7,
y- int=-2
this is equation c) y=-7x-2</span>
Answer:
None of the above...
Step-by-step explanation:
The first one is a cubic function and the v-shaped one is an absolute value function.
Given that the standard deviation, s = 2.3 and that there are 24 students, thus the degree of freedom is 24 - 1 = 23.
