QUESTION 1
Function – A function is the relationship that exists between an input and output such that one input has only one possible output. This implies that a function takes an input and produces an output based on the input (Cheney & Kincaid, 2012).
Examples
Linear function y = 2 x
Quadratic function
y = 2 x2
Third degree polynomial
y = 2 x3
Exponential function
y = e2x
Logarithmic function
y = log 2 x
Periodic function
y = sin x Domain of a function - The domain of a function is the set of inputs for which the output of the function exists (Cheney & Kincaid, 2012).The domain of linear function is (- ∞ to ∞), quadratic function is (- ∞ to ∞), ...
