Let f (x) = 1/x<br> and g(x) = x² – 3x. What<br> two numbers are not in the domain of fºg?
iren [92.7K]

For this case we have the following equations:

f (x) = \frac {1} {x}\\g (x) = x ^ 2-3x

We must find (f_ {o} g) (x):

By definition of composition of functions we have to:

(f_ {o} g) (x) = f (g (x))

So:

(f_ {o} g) (x) = \frac {1} {x ^ 2-3x}

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.

x ^ 2-3x = 0\\x (x-3) = 0

So, the roots are:

x_ {1} = 0\\x_ {2} = 3

The domain is given by all real numbers except 0 and 3.

Answer:

x other than 0 and 3

Determine the value of B such that the line defined by 8x + By + 92 = 0 passes through the point (-4,12).
zvonat [6]
8x + By + 92 = 0

(-4; 12) ⇒ x = -4; y = 12

subtitute

8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0    |subtract 60 from both sides
12B = -60    |divide both sides by 12

B = -5
