Answer:
1. Plug values into table inside calculator.
You can acess table by pressing [STAT] > Edit...
2. Use ExpReg function to generate equation.
[STAT] > CALC > scroll down to ExpReg
Answer:
y = -6 + 1.2*x is the answer I would use, but see the note below.
Step-by-step explanation:
Let x = the number of minutes.
Let y = the temperature at any given time.
y = -6 + 1.2*x
This is the equation that you would use if you were calculating y with a calculator. If you are in a chemistry class it should be written as
y = - 6°C + 1.2°x/ min
The answer to the problem is as follows:
<span>Well isn't the range of y=cos(u) is [-1,1]
So the max value for y=cos(u) is 1
And the min value for y=cos(u) is -1
--
So the max value for f(x)=4cos(u) is:
</span>
<span>f(u)=4cos(u)
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
