Use the following exponential function to answer the questions. y = 3\left(\frac{1}{7}\right)^x + 19\pi (a) Find the domain of the function. Write your answer in interval notation. (b) Find the coordinates of the y-intercept of the function. Remember to give an exact answer. No credit will be given for approximations. ( ) (c) Find the horizontal asymptote of the function. $\bigcirc$ y = -19$\pi$ $\bigcirc$ y = 0 $\bigcirc$ y = 3 + 19$\pi$ $\bigcirc$ y = 3 $\bigcirc$ y = 3 - 19$\pi$ $\bigcirc$ y = 19$\pi$

Consider the function f(x)=3sin(π/3(x−2))+7. State the amplitude A, period P, and midline. State the phase shift and vertical translation. In the full period [0, P], state the maximum and minimum y-values and their corresponding x-values.
