The expression
represents an exponential function, where constants a and b, and variables x and y indicate the rate of growth or decay as x varies.
The expression
represents an exponential function, where a and b are constant numbers, and x is the independent variable while y is the dependent variable. In such functions, the variable x appears as an exponent, and that is why it is called 'exponential.'
The base b is a positive number, and it determines the rate at which the function grows or decays. The coefficient a affects the steepness and direction of the graph.
If a student is given an expression like
, to find the value of y when x is 1, they would substitute 1 for x to get
, which simplifies to y=2*3, resulting in y=6.
