Answer:
Step-by-step explanation:
The domain of a function is all possible values for x.
There are restrictions on x.
The square root of a number can be undefined if that number is less than 0.
The value of x is all real numbers greater than or equal to 0.
Answer:
<em>The zero of the line is (2,0)</em>
Step-by-step explanation:
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as:
We are given the points (1,-3) and (4,6). Substituting:
Operating:
The zero of this line can be found by making y=0 and solving for x:
0+3=3(x-1)
3=3x-3
Adding 3:
6=3x
Solving:
x = 2
The zero of the line is (2,0)
