Answer:
8+2/2
= 5
-7+1 / 2
= -3
(5,-3) is the correct answer
The answer would be:
-7sqrt(6x)/4x^3
B...
|-24+6|=18
Same for the other one.
Answer:
Problematic x is x = 1
Step-by-step explanation:
Equation:
xy= 2x + y + 1
xy - y = 2x + 1
y(x-1) = 2x + 1
y = (2x+1)/(x-1)
The problematic x is such that when the denominator of the function is 0
x - 1 = 0
x = 1 (the problematic x)
So the domain of f is: x is the subset of R (real number) with the exception of x =/ 1 (x not equal to 1)
To prove this, we can plot the graph and in the graph we can see that as the value of x approaches from negative values to 1, y value will approaches negative infinity, and as the value of x approaches from large positive numbers, y value approaches infinity.
In other words, we'll see an assymptote at x=1
To prove that it is a function, we can do vertical line test by drawing vertical lines accross the graph. We'll see that each line crosses the equation line once hence proving the equation as a function
