Use the Given Information to Write an Exponential Equation for Y

Multiple Choice

Use the given information to write an exponential equation for y. Does the function represent exponential growth or exponential decay? $\frac { d y } { d t } = 2 y , y = 10 \text { when } t = 0$

A) $y = 10 e ^ { 2 t } , \text {expontial decay }$
B) $y = 10 e ^ { 2 t } , \text {expontial growth }$
C) $y = 10 e ^ { t } , \text { expontial decay }$
D) $y = e ^ { 2 t } , \text { expontial growth }$
