1. Given the function f(x) = 3x - 5, find:
a) f(2)
b) f(-4)
c) f(0)
2. If g(x) = x² + 2x - 1, evaluate:
a) g(3)
b) g(-1)
3. In the function notation f(x), 'f' represents the of the function, and 'x' represents the .
4. If f(x) = 7, this means the value of the function is 7 when the input is x.
5. The statement f(a) = b means that when the input to the function f is 'a', the output is ' '.
6. Which of the following statements is true about function notation?
f(x) means f multiplied by x.
f(x) represents the output of the function when the input is x.
f(x) is an equation that always equals zero.
f(x) can only be used for linear functions.
