<u>Composite Function</u>
Suppose f(x) and g(x) are real functions, the composite function named
is defined as:

The composite function can be found by substituting g into f.
We are given these functions:



Find:
a) h(g(x))
Substituting g into h:

b) h(g(f(x))
First we find g(f(x)):

Operating:

Simplifying:

Now find h(g(f(x)) replacing the above equation into h:

Simplifying and rearranging:


Answer:
Square pizza
Step-by-step explanation:
To obtain which pizza is the best buy:
Cost of square pizza :
AED 80
side length, s = 26cm
Area of square, A = s²
A = 26² = 676 cm²
1 AED of square pizza gives : 676 / 80 = 8.45 cm²
Cost of circular pizza :
AED 80
Radius, r = 28cm
Area of circle, A = πr²
A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²
1 AED of circular pizza gives : 616 / 80 = 7.7cm²
Hence, square pizza is the better buy ;
8.45cm² > 7.70 cm²
