Which type of function correctly describes the exponential function
g(x)=3(4)^x-5

See below.

Step-by-step explanation:

This function g(x) = 3(4^x) - 5 is an exponential function since it has a variable as an exponent. It has a initial value of 3 and a multiplicative rate of change of 4. The function itself when x = 0 is y = -2.

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
