Answer:
all real numbers expect 1.
Step-by-step explanation: This is a rational function. when we usually the find the domain of a rational function we would look at the bottom because you don't want the denomonatior to be zero because dividing by zero in math makes the range undefined. so we use the equation and set it up to zero to find the domain. 1-x=0 -x=-1, divide by -1 and we get 1. So x can be any numbers expect 1. Interval notation: (-∞,1)∪(1,+∞)
The slope is 1/-26 so y+16=1/-26(x-19)
Answer:
First option / a - y = 2x - 2
Step-by-step explanation:
We can tell it'll either be the first one or the second one as the line intercepts the y-axis at -2, so the b will be -2.
The line goes up 2 and over 1, so the slope will be 2. Putting all the pieces together gives us the first option of y = 2x - 2.

<em>Identify</em>
f(x) = -1x - 4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = -1(-3) - 4
- Multiply: f(-3) = 3 - 4
- Subtract: f(-3) = -1
The answer is -148≤ F≤ -103!
