If f(x) = x^2 - 25 and g(x) = x - 5, what is the domain of (f/g)(x)

zhuklara [117]

Answer:

The domain of the function is all real numbers except number 5

Step-by-step explanation:

we have

$f(x)=x^{2}-25$

The domain of f(x) is all real numbers

$g(x)=x-5$

The domain of g(x) is all real numbers

$(f/g)(x)=\frac{f(x)}{g(x)}$

substitute

$(f/g)(x)=\frac{x^{2}-25}{x-5}$

Remember that

The denominator cannot be zero

For x=5 the denominator is equal to zero

therefore

The domain of the function is all real numbers except number 5

How do you find 3w-6w+3w×7×7×6×5÷9+2

Viktor [21]

Let's remember orders of operations as we go through the craze of this problem.
We need to multiply or divide from left to right.
3w-6w+3w×7×7×6×5÷9+2
3w-6w+21w×7×6×5÷9+2
3w-6w+147w×6×5÷9+2
3w-6w+882w×5÷9+2
3w-6w+4,410w÷9+2
3w-6w+490w+2
-3w+490w+2
487w+2
To check that we simplified the expression right, I like to put in 1 for w and test it in the original expression and then the simplified expression (not needed).
487+2=489
3-6+3×7×7×6×5÷9+2=489
So that expression equals 487w+2.
