Answer:
When x = 1, (f◦g)(x) is -2.
Step-by-step explanation:
Composite function:
The composite function of f and g is given by:

In this question:

Composite function:
The composite function is:

At x = 1

So
When x = 1, (f◦g)(x) is -2.
12———-100%
8 ———— x
X=(8*100)/12=800/12=66.66%
Then discount percent is 100-66.66=33.33%
