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
