The formula C − 5 sF 2 32d, where F > 2459.67, 9 expresses the Celsius temperature C as a function of the Fahrenheit temperature F. Find a formula for the inverse function and interpret it. What is the domain of the inverse function?

Respuesta :

Answer:

a) The inverse of the function is [tex]F=\frac{9}{5}C+32[/tex]

b) The domain of the inverse function is C>1348.70.

Step-by-step explanation:

Given : The formula [tex]C=\frac{5}{9}(F-32)[/tex], where [tex]F>2459.67[/tex] express the Celsius temperature C as a function of the Fahrenheit temperature F.

To find : a) A formula for the inverse function and interpret it.

b) What is the domain of the inverse function?

Solution :

a) The formula [tex]C=\frac{5}{9}(F-32)[/tex]

The inverse function of the given formula is the value of F.

Taking F to one side and rest term to other side,

[tex]\frac{9}{5}C=(F-32)[/tex]

[tex]\frac{9}{5}C+32=F[/tex]

Therefore, The inverse of the function is [tex]F=\frac{9}{5}C+32[/tex]

i.e. Fahrenheit temperature F as a function of the Celsius temperature C.

b) The domain of the inverse function.

We have given, [tex]F>2459.67[/tex]

Substituting in the formula,

[tex]C=\frac{5}{9}(F-32)[/tex]

[tex]C=\frac{5}{9}(2459.67-32)[/tex]

[tex]C=\frac{5}{9}(2427.67)[/tex]

[tex]C=1348.70[/tex]

The domain of the inverse function is C>1348.70.
