Answer:
14/5
Step-by-step explanation:
That " • " signifies multiplication.
g(x) = (x + 1) / (x - 2) and h(x) = 4 - x are to be multiplied together to obtain (g·h)(x):
(x + 1)(4 - x)
(g·h)(x) = --------------------
x - 2
This could be simplified.
But our task is to evaluate this product function at x = -3. So we replace each instance of x with -3:
( -3 + 1 )( 4 - [-3] ) (-2)(7)
(g·h)(-3) = -------------------------- = ----------- = 14/5
-3 - 2 -5
Answer:
Step-by-step explanation:
multiply each side by 
which comes out to
I think it is 32, bc the value of x is 20 so your problem would look like this; 2 ( (20) - 4 )
X(exponent 2) - x - 6
------------------------- =
x(exponent 2) -4
(x-3)(x+2)
------------- =
(x-2)(x+2)
Cancel out the x + 2 factors.
x-3
