Decide if the function is an exponential function. if it is, state the initial value and the base. (2 points)
y = - 7.3 ⋅ 2x

exponential function; base = - 14.6; initial value = 1

exponential function; base = x; initial value = - 7.3

not an exponential function

exponential function; base = 2; initial value = - 7.3

Long division setup showing an incomplete calculation. 12 is in the divisor, 6839 is in the dividend, and 5 hundreds and 6 tens is written in the quotient. 6000 is subtracted from 6839 to give 839. an unknown value represented by a box is being subtracted from 839. what number should be placed in the box to complete the division calculation?
