Function notation is another way to express the y value of a function. Therefore, when graphing, we can always label the y-axis as f(x) too. It might look confusing, but let us show you how to deal with it.

Basic concepts: Solving linear equations using multiplication and division, Solving two-step linear equations: $ax + b = c$, ${x \over a} + b = c$, Solving linear equations using distributive property: $a(x + b) = c$, Solving linear equations with variables on both sides,

- 6.The temperature below the crust of the Earth is given by C(d) = 12d + 30, where C is in Celsius and d is in km.

i.) Find the temperature 15 km below the crust of the Earth.

ii.) What depth has a temperature of $186^\circ$C?
