En este problema observamos que la temperatura del congelador desciende <em>linealmente</em> con el paso del tiempo, es decir, conforme al siguiente modelo:
(1)
Donde:
- Temperatura inicial, en grados Celsius.
- Cambio total de la temperatura, en grados Celsius.
- Cambio total en el tiempo, en horas.
- Tiempo, en horas.
Si sabemos que 
, 
. 
y 
, entonces la temperatura del congelador al completarse la primera hora es:
El congelador tenía una temperatura de -1 °C a la primera hora.

Answer:
we have
using a graph tool
see the attached figure
the domain of the function is all real numbers------> the interval is (-∞,∞)
the range of the function is --------------------------------> the interval (-∞,9]
therefore
the answer is
The range of the function is all real numbers less than or equal to 9
Step-by-step explanation:
3.95 Because 3 5/6= 3.83 and 3 4/5 = 3.8
We get the value of h and k as 9 and -8
The quadratic function g(x) = a(x - h)^2 + k, if a is not equal to 0,which means that equation has a quadratic value then it is said to be in standard quadratic form.
If a is positive, then the graph opens upwards,
If a is negative, then it opens downwards.
The line of symmetry of the quadratic equation is the vertical line x = h, and the co-ordinate of the point of vertex is (h,k).
We are given the co-ordinate of the vertex point in the question and hence all that is required is to equate it.
Therefore, the values of h and k are 9 and -8 in the given equation in vertex form
