The high temperature one day was 30°f. then
the temperature dropped 23 degrees during the
night. does the expression 30+ (-23) represent
the temperature at night? explain.

yeah and

step-by-step explanation:

you know what it isnt great cheating

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
