Given
  h(x) = f(x)·g(x) = -x² -3x +4
Find
  Possible equations for f(x) and g(x)

Solution
  h(x) factors as -(x -4)(x +1)
There are an infinite number of possibilities for f(x) and g(x). Some of the simpler ones are ...
  f(x) = 4 -x; g(x) = x +1
or
  f(x) = -x -1; g(x) = x -4
or either of this with f and g swapped.

For some q(x), you can also have ...
  f(x) = (4 -x)×q(x); g(x) = (x +1)/q(x)
again, possibly with f and g swapped

Assume f(x)=2x+8 and g(×)=5 what is the value of (g o f)(3)
RUDIKE [14]
We first need to find f(3).

f(3) = 2(3) + 8

f(3) = 6 + 8

f(3) = 14

We now want g(f(3)).

We know that f(3) is 14.

We also know that g(x) is 5.

As you know, 5 is a constant. No matter what the value of x is for g(x), it will not change the value of g(x).

So, g(f(3)) = g(14) = 5.

Answer: g(f(3)) = 5.

Find the length of side x in simplest radical form with a rational denominator.
schepotkina [342]

Answer:

x = 2√3

Step-by-step explanation:

The sides of a 30-60-90 triangle are always in the ratio 1:√3:2.

The length of the side opposite the 90° angle is 4, so the length of the side opposite the 30° angle is 2 and the length of the side opposite the 60° angle is 2√3.

x = 2√3
