Exponential parent function increasing or decreasing. Recall the table of values for a function of the form f (x) = b x whose Asymptote: an imaginary line that the function gets really close to but never touches or crosses {hint: look @ } Write this as an equation: : when Identify: domain, range, y-intercept, x-intercept, Again, because the input is increasing by 1, each output value is the product of the previous output and the base or constant ratio 1 2. For example, if a population increases by 5% every year, then the growth factor b is There is no x-intercept because the function does not ever cross the x-axis. Uh oh, it looks like we ran into an error. 25 is between zero and one, we know the function is decreasing. The graphs for exponential growth and decay functions are displayed below as x increases, the output values increase without bound; and as x decreases, the output values grow smaller, approaching zero.
