Answer:
- When we are having a rational expression i.e. a expression of the type:

Where f(x) and g(x) are polynomial functions.
Now the domain of this rational expression is whole of the real numbers except the points where the function g(x) will be zero.
Hence we have to exclude the points where the given denominator quantity is zero.
- Let us consider an example as:
Let R(x) denote the rational function as:

Now the domain of this rational function will be whole of the real line minus the points where the denominator is zero.
We know that (x-2)(x-3) is zero when x=2 or x=3.
Hence, the domain of R(x) is: R- {2,3}.
Answer:
The first one is 120 and the second is 200
Step-by-step explanation:
The range value is the domain value times 40
Converting celsius to farenheit
C * 1.8 + 32
220 * 1.8 + 32 = 396 + 32 = 428 F....so 220 C = 428 F
so he set the oven for 428 F, when it was supposed to be set for 400 F
428 - 400 = 28.....28 degrees too hot
