Item 1 Question 1
The graph of which of the following functions does not belong with the other three?

$f\left(x\right)=3x^2+6x-24$

$f\left(x\right)=3x^2+24x-6$

$f\left(x\right)=3\left(x-2\right)\ left(x+4\right)$

$f\left(x\right)=3\left(x+1\right)^ 2-27$
Question 2
This is the only function that does not have x-intercepts at $x=$ Response area and $x=$ Response area and a vertex at (Response area , Response area).

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

72 is the mode because it shows up the most number of times
