compare and contrast quadratic and exponential function (using visuals/diagrams) . In your discussion, consider using the following talking points: first differences, quadratic, exponential, equation, graph, f(x)=x^2, f(x)=2^x.
Firstly, quadratic function is a polynomial with the highest degree of 2. That is, is always present there. While, exponential function has a variable as it exponent e.g. .
Differences:
When the independent variable changes by a constant amount, quadratic functions have constant second differences, while exponential functions have a constant ratio.
Graph:
Taking and to be the example for quadratic and exponential function respectively. We see the graph as follows
This is the graph of
This is the graph of
We see that the quadratic graph makes/form a Parabola (whether facing up or down). While the exponential function graph rises or falls freely in One Direction.
