1. Evaluate the exponential equation for three positive values of x, three negative values of x, and at x=0. Transform the second expression into the equivalent logarithmic equation; and evaluate the logarithmic equation for three values of x that are greater than 1, three values of x that are between 0 and 1, and at x=1. Use the resulting ordered pairs to plot the graph of each function and show your work.
Y= 4^-x , x= 4^-x
2. Solve the problem.
Use the formula L = 10.log I/IO∙ where the loudness of a sound in decibels is determined by I, the number of watts per square meter produced by the sound wave, and I0 = 10^-12 W/m^2,.What is the intensity of a noise measured at 80 dB?
