Answer:
exponential
Step-by-step explanation:
An exponential function is defined as a function with a positive constant other than 1 raised to a variable exponent. A function is evaluated by solving at a specific input value. An exponential model can be found when the growth rate and initial value are known.

About 95% of a normal distribution lies within two standard deviations of the mean, so 5% lies without, and since the distribution is symmetric, 2.5% lies to either side. This means
