Functions and Function Notation
1. If f(x) = 3x - 8 and g(x) = 2(x + 4)² - 3 , then determine:
i) f(5); ii) g(a + 4); iii) 3f(7); iv) 2f(3a+1)-g(a-1)
2. If f(x) = x2 – 3x – 12, then determine x such that f(x) = 16.
3. A teacher gives a test to her students. The highest mark in the class is 180 and the lowest mark in the class is 60. Determine a linear function such the highest mark in the class is 95 and the lowest mark in the class is 55.
