Answer:
<em>The a and the base value</em>
Step-by-step explanation:
<em>Depending on the number of the a or b value, the graph can be completely altered! In a standard exponential function, the b value is 2</em>
<em>An exponential function with both an a and a B value looks like this:</em>
<em> </em>
<em>The a value is the starting point of the exponential function. Not all function will have starting points, mind you! The a value can be negative or positive, which would affect the point which the graph of the exponential function starts.</em>
<em>The b value is like the 'rate of change' for the exponential function. It can also be positive or negative -- depending on the sign of the b value, the function can decrease of increase.</em>
