Math Problem Statement

Divide the functions f(x) = x + 2 and g(x) = 2x + 4.

Solution

The image shows two functions f(x)=x+2f(x) = x + 2 and g(x)=2x+4g(x) = 2x + 4 under the heading "DIVIDE."

To divide these two functions, we perform the following operation:

f(x)g(x)=x+22x+4\frac{f(x)}{g(x)} = \frac{x + 2}{2x + 4}

Now, simplify the expression:

x+22x+4=x+22(x+2)\frac{x + 2}{2x + 4} = \frac{x + 2}{2(x + 2)}

Since x+2x + 2 appears in both the numerator and the denominator, you can cancel it out, giving:

f(x)g(x)=12forx2\frac{f(x)}{g(x)} = \frac{1}{2} \quad \text{for} \quad x \neq -2

The restriction x2x \neq -2 comes from the fact that g(x)=0g(x) = 0 when x=2x = -2, making the expression undefined at that point.
