- 2sum(f + g)(x) = f(x) + g(x)
- 3difference(f – g)(x) = f(x) – g(x).
- 4product,(f · g)(x) = f(x) · g(x).
- 5quotient(f/g)(x) = f(x)/g(x)

- 91. Mark started selling snacks in the nearby school. In one day he spends ₱350 for rent and ₱25 for each snack item he prepares. His expenses in a single day can be expressed as the function C(x)=25x+350, where x is the number of items and C(x) is his daily expenses in pesos. How much are his expenses if he prepares: a. 100 snack items? b. 250 snack items?a. 2850
b.6600 - 10Example 1. Given f(x) = 2x - 4, find the value of the function if x = 3.f(3) = 2
- 11Example 2. Given q(x) = x2 + 2x + 2, find q(-3).q(-3) = 5
- 12Example 3. Given f(x) = Lx⅃ + 1, find f(3.5)f(3.5) = 4
- 13Example 4. Given f(x) = 5x + 1, find f(h+1).f(h+1) = 5h + 6
- 14Example 5. Evaluate the function q(x) = x2 – 2x + 2 at q(2x - 3)q(2x - 3) = 4x2
