Felicity set the thermostat in her living room to 68°F. The room temperature t, in degrees Fahrenheit, m minutes after the therm
1 answer:
Answer with explanation:
Temperature in the living room =68°F
The equation which satisfies ,the room temperature t, in degrees Fahrenheit, m minutes after the thermostat is activated, satisfies
t=2 Cos (0.21 m) +68----------(1)
⇒To determine the period of the function
Z= A cos (sx+q)+r
As period of cos x is 2 π.
So,the given function has period
So, the period of function 1, is given by
⇒The meaning of period of the function is that after every period of the temperature of the room increases or decreases by an integer equal to 2.
⇒Cosine function has maximum value of 1 , and Minimum value of -1.
-1 ≤ Cos x ≤ 1
So, the Maximum value of function = 2 ×1+68°=70°----Maximum Temperature
And, the minimum value of function = 2 ×(- 1)+68°=66°----Minimum Temperature

Answer:
By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Step-by-step explanation:
We need to explain why the function of is neither even or odd
First we will understand, when the function is even and odd
Even function:
<em>A function is even if f(-x) = f(x) </em>
Odd function:
<em>A function is odd if f(-x) = -f(x) </em>
So, if we get the above result by putting x = -x, then we can say that the function is even or odd.
If we don't get any of the above results then the function is neither even nor odd.
So, for the given function:
Put x = -x
So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
