The temperature is 50 degrees fahrenheit. the temperature will decrease by 4 degrees f. each hour. let h be the number of hours. when will the temperature be below 32 degrees f.? (the pic has the options for the answer.)

The correct answer choice is B

Option B is correct

Step-by-step explanation:

Here, h be the number of hours.

As per the statement:

The temperature is 50 degrees Fahrenheit.

⇒Initial temperature = 50 degrees Fahrenheit

It is also given that:

The temperature will decrease by 4 degrees F each hour.

1 hour temperature will be = -4 degree F

then;

In h hour temperature =  -4h degrees F

We have to find the the temperature be below 32 degrees F.

Total Temperature be below 32 degrees F means:

where, h represents the number of hours.

Therefore, the  the temperature below 32 degrees F will be

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.
