Calculate $f(-1)$ for the graph below.

To convert a temperature from Celsius to Fahrenheit, we use the formula: $F\left(C\right)=\frac{9}{5}C+32$. Use the formula to calculate the temperature in degrees Fahrenheit at which water boils.

To convert a temperature from Celsius to Fahrenheit, we use the formula: $F\left(C\right)=\frac{9}{5}C+32$. The average body temperature of the dog is $38.{75}^{°}\mathrm{C}$. Convert this to degrees Fahrenheit.

Cookies are generally baked at ${350}^{°} \mathrm{F}$. Convert this to degrees Fahrenheit (correct up to two decimal places). To convert a temperature from Celsius to Fahrenheit, we use the formula: $F\left(C\right)=\frac{9}{5}C+32$.

A British telecommunications company offers the following roaming data package to its customers: a flat fee of $\pounds 25$ plus $\pounds 10$ per gigabyte of data. Express the total cost, $\mathrm{C}$, as a function of the number of gigabytes of data $g$.

A British telecommunications company offers the following roaming data package to its customers: a flat fee of $\pounds 25$ plus $\pounds 10$ per gigabyte of data. What values of $g$ do not make sense in this context?

A British telecommunications company offers the following roaming data package to its customers: a flat fee of $\pounds 25$ plus $\pounds 10$ per gigabyte of data. State the notation that could be used to find the roaming cost for a trip where $14$ gb of data is used? Calculate this value.

A British telecommunications company offers the following roaming data package to its customers: a flat fee of $\pounds 25$ plus $\pounds 10$ per gigabyte of data. State the notation that could be used to find the number of gigabytes of data one can use for a total bill of $\pounds 100$. Calculate this value.
