Solve for x over the real numbers:2 x^2 - 3 x - 2 = x + 4
Subtract x + 4 from both sides:2 x^2 - 4 x - 6 = 0
The left hand side factors into a product with three terms:2 (x - 3) (x + 1) = 0
Divide both sides by 2:(x - 3) (x + 1) = 0
Split into two equations:x - 3 = 0 or x + 1 = 0
Add 3 to both sides:x = 3 or x + 1 = 0
Subtract 1 from both sides:Answer:  x = 3 or x = -1

Which of the following functions is graphed below ? (:
Alekssandra [29.7K]
C is the answer.  By only looking at the domain (the stuff on the right in the functions), you can see that the first equation has a hole at x=2, meaning it does not have a value here at x=2.  When x<2, there are values for the 1st function.  When x>2, there are values for the second function, as well as when x=2

Evaluate g(n-7) if g(x) =x^2-5 / 3x
aleksandrvk [35]

Answer:

g(n-7)=\frac{n^2-14n+44}{3n-21}

Step-by-step explanation:

The given function is

g(x)=\frac{x^2-5}{3x}

To find g(n-7), we substitute x=n-7 to obtain;

g(n-7)=\frac{(n-7)^2-5}{3(n-7)}

Expand the parenthesis to obtain;

g(n-7)=\frac{n^2-14n+49-5}{3n-21}

Simplify:

g(n-7)=\frac{n^2-14n+44}{3n-21}
